I have a Maxtor 20 GB 7200 RPM harrddrive
Just wondering if these results meet the Standards

Settings:
/dev/ide/host0/bus1/target0/lun0/disc:
setting 32-bit I/O support flag to 1
setting using_dma to 1 (on)
setting xfermode to 68 (UltraDMA mode4)
I/O support = 1 (32-bit)
using_dma = 1 (on)

Results:
/dev/ide/host0/bus1/target0/lun0/disc:
Timing buffer-cache reads: 128 MB in 0.96 seconds =133.33 MB/sec
Timing buffered disk reads: 64 MB in 2.47 seconds = 25.91 MB/sec

The Results Vary by Around 10MB
(highest was 140.83 for cached and 28 for non-cache)

Is this Normal?

Ae there sime tests I can run that would show some effcts of dma? Here's waht I started with:
Code:
Timing buffer-cache reads:   128 MB in  0.80 seconds =160.60 MB/sec
 Timing buffered disk reads:  64 MB in 10.40 seconds =  6.15 MB/sec
Then I tryed hdparm -c 1 -d 1 /dev/hda and got
Code:
Timing buffer-cache reads:   128 MB in  0.81 seconds =157.44 MB/sec
 Timing buffered disk reads:  64 MB in  1.67 seconds = 38.39 MB/sec
Then setting udma mode 5 didnt change much. After setting that i got
Code:
Timing buffer-cache reads:   128 MB in  0.82 seconds =156.29 MB/sec
 Timing buffered disk reads:  64 MB in  1.70 seconds = 37.62 MB/sec
which is virtually no diff. but its cool that i got a 6x increase with that. Seagate 7200 80gig. btw, maybe this should be moved to tweaks, even though it started as hardware?

This is for those of you with a kt266/82XX chipset:

Contrary to what you might think this chipset was not fully supported until recently, when code submitted by Vojtech Pavlik was incorporated into the 2.4.19-pre9.patch . None of the kernels that you can emerge through portage have that patch, so if you want full support for that chipset you have to build your own patched kernel. Keep in mind that this patch is a work in progress.

So what you need to do is emerge vanilla sources, then head over to ftp.kernel.org get 2.4.19-pre9.patch and apply that patch to the vanilla sources.

Optionally you can also get the pre-emptive kernel patch and apply that AFTER you applied the patch mentioned above.

I did this and my system (Soyo Dragon +, kt266a/VT8233CE) runs smoother than ever:)

Really? my soyo dragon runs fine with 2.4.19-gentoo-r7. My drives work decently.

The patch is already in gentoo-sources.

You only have to compile support for VIA chipset in the kernel.
I forgot to do that first and my system overall speed was really slow, although I switched dma on to the hdd...

omg, is this normal:
hdparm -tT /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.50 seconds =256.00 MB/sec
Timing buffered disk reads: 64 MB in 1.59 seconds = 40.25 MB/sec

I have a 40 GB Seagate, 7200 rpm, using xfs how said before. seems to be great performance

WOAH

Here's a before
Code:
Timing buffer-cache reads: 128 MB in 0.42 seconds =159 MB/sec
Timing buffered disk reads: 64 MB in 2.76 seconds = 3.23 MB/sec


And amazeingly, here's after "hdparm -c3 -m16 -X69 -d1 -u1" on /dev/hde and /dev/hdg:

Code:
Timing buffer-cache reads: 128 MB in 0.42 seconds =160 MB/sec
Timing buffered disk reads: 64 MB in 2.76 seconds = 40.25 MB/sec


Both of those above are an average of about 4 tests on both hard drives.... none of them were off more then 1 MB/sec between every other one.

Question:
What's my bottlekneck that's causeing the Timing buffer-cache read to top out at 160 MB/sec? I've been people with over 200. This ATA/100 UDMA5 on 2 7200RPM Maxtor 60GB HD's w/ 2MB Cache.

Another question that's kinda scary:
I booted into single user mode to try this the first time, and when I rebooted back into normal mode, none of the settings were saved. In fact, I noticed that every time I changed it, it wouldn't be saved after a reboot. So I just aded the command to my /etc/conf.d/local.start file and it works fine now. BUT, one major thing... when I set it to UDMA, even though my mobo is suppost to support it, I get the following error in /var/log/messages:

Code:
ide2: Speed warnings UDMA 3/4/5 is not functional.
ide3: Speed warnings UDMA 3/4/5 is not functional.


I got to reading about it on Google, and I found that UDMA has been disabled in my IDE chipset b/c it's not stable? How can I get around this, and what would happen if I forced it to run at UDMA5 all the time, which I can do with the local.start script.

Is there somewhere I can put the same thing that's in my local.start script to get hdparm to change the HD mode before everything starts loading so my system will boot up faster?

I'm having the same problem.

My mb (abit VT6X4) support ATA66 (that would be udma4).

My HD (Maxtor 91531U3) supports ATA66:

Code:
DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 *udma4


But I get the following warning when I do hdparm -X 68:

Code:
ide0: Speed warnings UDMA 3/4/5 is not functional.


The performance i'm getting so far:

Code:

Timing buffer-cache reads:   128 MB in  0.89 seconds =143.82 MB/sec
 Timing buffered disk reads:  64 MB in  2.66 seconds = 24.06 MB/sec


When I read this thread, that isn't a very bad performance, but I wonder if it would be any better if I was able to set -X 68.

Could the CDRom drive (also on ide0) prevent this?

On ide1 there's a cd burner (hp9100+), so I think that is why they put (didn't built this machine myself) on ide0.

Someone an idea on how to force udma4 performance?

Ruud

[EDIT]
so oke i was a bit hasty with the keyboard. Turns out I didn't have VIA support compiled in the kernel. Did that and now -X68 doesn't give the error/warning. However, performance hasn't improved a bit[/EDIT]

Don't get all caught up in the numbers here. The point of this all isn't to get
the highest numbers you can, its really to get the the controller and chipset
set up to transfer data as fast as the drive can. As soon as you get the
controller set up to run as fast as the drive can, you will not see any more
significant performance increases. I have an old 7200 rpm udma 66 drive
that will only transfer data at 16 mb's a sec when configured correctly. Its
that the drive was one of the first to come out at that speed, and thats as
fast as the heads can read the data from the platters. I have a new one
thats udma 133 that reads at 46 mb's a sec.
You ought to test your computer at these different settings by running
something like
time dd if=/dev/zero of=1000mbfile bs=1000k count=1000
That will time your machine writing a 1 gig file. Be sure to delete it.
thats one way you can see the real performance differences.
By the way, I've found that dd transfers much faster with the larger
block sizes, so i changed the defaults in the code on my machine and
recompiled it. Call me crazy.

Hmm..

Ok - I have tried applying optimizations:

Drive conforms to: ATA/ATAPI-5 T13 1321D revision 1: 1 2 3 4 5


sudo /sbin/hdparm -u 1 -m 16 -c 1 -d 1 /dev/hde

Yet i still only get:

/dev/hde:
Timing buffer-cache reads: 128 MB in 1.02 seconds =125.00 MB/sec
Timing buffered disk reads: 64 MB in 1.67 seconds = 38.25 MB/sec

Any ideas why it isn't any better ? :(

hey, this is quite good :)
you might want udma6, though I dont know if you will actually notice any difference...

btw, I see everyone here is using -m 16 ...
Always been using -m 32 (yes my disks do suppor that :)

btw, a quote from the hdparm manual :

Quote:

Western Digital recommends lower settings of 4 to 8 on many of their drives, due tiny (32kB) drive buffers and non-optimized buffering algorithms.
The -i flag can be used to find the maximum setting supported by an installed drive (look for MaxMultSect in the output).


this is probably not true any more with modern disks, but you never know :)

Sp4rky, you were lucky you didn't have faster drives. The reason for the limitation, and kernel option, is that a lot of machines with buggy Via chipsets can have "massive file corruption" 8O if UDMA modes > 2 (33MB/s) are enabled.

I found out the hard way over a year ago. Everything tested good until I transferred over 100 MB. at once at >32 MB/s. UDMA 2 can never sustain this rate. It is barely possible with UDMA 4, fairly common with UDMA 5. I did a good bit of testing settings before I used them for real work.

Until I had a disk where data came off the head fast enough to sustain that rate it wasn't even possible. (Forget the big numbers on the outside of the box.) If I hadn't had >100 MB. of RAM there wouldn't have been such a transfer anyway. Other people had no trouble until they installed a new sound card. It isn't worthwhile to find out what you can get away with.

Gentoo kernels have the Via option set by default. People, don't turn it off if you ever plan to run it on a machine with a Via 686a or 686b chip. (Some may still be sold AFAIK. ) The easy option for software is to permanently limit performance. Gentoo is different.

Nice! My new numbers:

Code:

/dev/hda:
 Timing buffer-cache reads:   128 MB in  0.54 seconds =237.04 MB/sec
 Timing buffered disk reads:  64 MB in  1.59 seconds = 40.25 MB/sec


I am also interested in if there is anything like this for the SCSI side. Currently my ATA is outperforming my SCSI. :(

Don't forget that buffer-cache reads only use memory access (no access to the disk)

from man hdparm
Code:

-T     Perform  timings  of cache reads for benchmark and comparison pur-
              poses.  For meaningful results, this operation should be  repeated
              2-3  times  on  an otherwise inactive system (no other active pro-
              cesses) with at least a couple of megabytes of free memory.   This
              displays the speed of reading directly from the Linux buffer cache
              without disk access.  This measurement is essentially  an  indica-
              tion  of the throughput of the processor, cache, and memory of the
              system under test.  If the -t flag is also specified, then a  cor-
              rection  factor  based  on  the outcome of -T will be incorporated
              into the result reported for the -t operation.


This is an interesting link (I've posted in another thread also)

Bloody Bastard: thank you for enlightening me. I did not know that. Now it makes sense that my 2 drives would have similar ratings for buffered cache reads. :P

Andrew

Can anyone beat my 45.98MB / sec? just curious. I run ReiserFS with notail on my WD special edition, on Epox 8KHA+ board. :?:

You're welcome 8)

BTW, you should run benchmarks more than one time to get relevant results. I would say at least 7 times (I would be more confortable with 20), but I'm not taking in account statisc rules -- just magic numbers.

I ran it 8 times, and they were all within 1MB/sec of that number, but I can post all if you want :P , but anyways, not that it is a competition, I am just happy that my $107 didn't go to waste, but actually got me a high proformance drive for once.

Hi, very interested thread. I have seen the same problems here.

I have 2 cases : 1 Compaq EVO N800c and a selfbuilt rack mounted server.

The Compaq EVO N800c uses an Intel 845 chipset on a vanilla RH7.3 kernel.
The selfbuilt server uses an Intel E7500 chipset on a tweaked 2.4.19 customkernel with 3ware 7500-12 controller support inbuilt.

Ok i used the following commands in HDparm for the ide-drive (maxtor 160gb 5400rpm):

[root@videoserver f1]# hdparm -X69 -d1 -u1 -m16 -c3 /dev/hda

/dev/hda:
setting 32-bit I/O support flag to 3
setting multcount to 16
setting unmaskirq to 1 (on)
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
setting xfermode to 69 (UltraDMA mode5)
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
using_dma = 0 (off)

The following benchmark on both /dev/hda through the ICH2 controller and /dev/sda through the 3ware controller:

[root@videoserver f1]# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.28 seconds =457.14 MB/sec
Timing buffered disk reads: 64 MB in 14.51 seconds = 4.41 MB/sec

/dev/sda:
Timing buffer-cache reads: 128 MB in 0.29 seconds =441.38 MB/sec
Timing buffered disk reads: 64 MB in 0.48 seconds =133.33 MB/sec

I compiled the 2.4.19 kernel with support for the Intel Piix driver. And the 3ware card is on a 266MB max speed (64bitx33mhz). Could it be that there some switch to turn it from 32bit to 64bit ? so in fact its using 32bit mode now?

Anyway over to the portable. I was very dissapointet with the speed here. Its a 1.7ghz P4 with a 5400rpm toshiba drive. I hoped to get more than this:

[root@localhost root]# hdparm -Tt /dev/hda

/dev/hda:
Timing buffer-cache reads: 128 MB in 0.35 seconds =365.71 MB/sec
Timing buffered disk reads: 64 MB in 11.33 seconds = 5.65 MB/sec

[root@localhost root]# hdparm -c1 -d1 -u1 -X69 /dev/hda

/dev/hda:
setting 32-bit I/O support flag to 1
setting unmaskirq to 1 (on)
setting using_dma to 1 (on)
HDIO_SET_DMA failed: Operation not permitted
setting xfermode to 69 (UltraDMA mode5)
I/O support = 1 (32-bit)
unmaskirq = 1 (on)
using_dma = 0 (off)

Well i see the same problem here. Thou i use a stock kernel from RH.73 i would guess the 845 chipset was supported in DMA mode and not in Generic IDE mode.

When i do a hdparm -I /dev/hda i get:

[root@localhost root]# hdparm -I /dev/hda

/dev/hda:

Anyone have any idea what i should do to add DMA support to the kernel for both machines? Even on the portable it locks up when i try to send much data on the pure-ftpd thats running on it. Well it doesnt lockup but it sorta stops for a few seq's even if TOP says pureftp uses 25% cpu and not 100%

best regards dragmore

The problem may be in your network card. eepro100 is known by having some problems.... make a search in Gentoo forums and I 'm sure you'll find some valuable info about it.
