this is a pretty good thread...
figured i'd post a solution to a problem i had while trying to enable udma mode 6 on my drive. could not get it to do anything over udma 33, turned out it was because i didn't have the Master hdd on the end of the ide cable. worked fine after i put it on the end. udma 133 now. (i feel dumb lol)

/dev/hda:
Timing buffer-cache reads: 1824 MB in 2.00 seconds = 911.23 MB/sec
Timing buffered disk reads: 144 MB in 3.04 seconds = 47.42 MB/sec

the drive i have my Linux on is slave......

so ur saying that if i swapped my drives and put it as root and redo my fstab and grub.conf to apply accordingly then it would run better?

Hi,
I find strange behaviour with CD-RW( /dev/hdc) on ICH5 chip.
with:
Code:
unmaskirq    =  1 (on)
using_dma    =  0 (off)
keepsettings =  0 (off)
readonly     =  0 (off)
readahead    = 64 (on)

I get following speeds
Code:
 Timing cached reads:   1984 MB in  2.00 seconds = 991.16 MB/sec
 Timing buffered disk reads:   10 MB in  3.71 seconds =   2.70 MB/sec

now I enabled dma:
Code:
#hdparm -d 1 /dev/hdc
#hdparm /dev/hdc
 IO_support   =  1 (32-bit)
 unmaskirq    =  1 (on)
 using_dma    =  1 (on)
 keepsettings =  0 (off)
 readonly     =  0 (off)
 readahead    = 64 (on)
#hdparm -tT /dev/hdc
 Timing cached reads:   1952 MB in  2.00 seconds = 975.17 MB/sec
 Timing buffered disk reads:   10 MB in  3.70 seconds =   2.70 MB/sec

There is no difference in speed
Although my cd-rw supports udma2 mode.
Code:
# hdparm -I /dev/hdc
..............
ATAPI CD-ROM, with removable media
        Model Number:       SONY    CD-RW  CRX225E
..............
Standards:
        Used: ATAPI for CD-ROMs, SFF-8020i, r2.5
        Supported: CD-ROM ATAPI-2
...............
Capabilities:
        LBA, IORDY(cannot be disabled)
        DMA: mdma0 mdma1 mdma2 udma0 udma1 *udma2
             Cycle time: min=120ns recommended=120ns
        PIO: pio0 pio1 pio2 pio3 pio4
             Cycle time: no flow control=227ns  IORDY flow control=120ns


Also when I run cdrecord
Code:
#cdrecord -scanbus -dev=ATAPI:/dev/hdc
..........
Warning: The related Linux kernel interface code seems to be unmaintained.
Warning: There is absolutely NO DMA, operations thus are slow.
...........

Any idea why there is no difference after enabling dma?
Why cdrecord complains that there is no dma?
PS: system config
linux-2.6.9-rc2
configured with dma enabled
I result of harddisk(/dev/hda)
Code:
/dev/hda:
 Timing cached reads:   1940 MB in  2.00 seconds = 969.66 MB/sec
 Timing buffered disk reads:  170 MB in  3.01 seconds =  56.47 MB/sec

when i do a hdparm -tT /dev/hda i get these strange readings:
Code:
Timing cached reads: 2056 MB in 2.00 seconds = 1027.13 MB/sec
Timing buffered disk reads: 4 MB in 3.07 seconds = 1.30 MB/sec

when i test my other drive i get 990Mb/s and 35MB/s.

i've checked the hdparm -i outputs and the only difference is the BuffType= option.
On the a drive it is unknown and on the b drive it is DualPortCache.
How can i fix this, and get both my drives up to speed???

[EDIT]
sorry didn't realize it was an old thread.

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. :?:


Code:
# hdparm -Tt /dev/hdc

/dev/hdc:
 Timing cached reads:   1768 MB in  2.00 seconds = 882.37 MB/sec
 Timing buffered disk reads:  164 MB in  3.00 seconds =  54.60 MB/sec


with -d1X69c1u1m16 on the 120GB 7200rpm Ultra ATA/100 HDD of my laptop. Quite impressive, isn't it ?
BTW I'm using reiser4, but I don't know if this affects the results, because I also have ntfs, fat32 and ext2 partitions on this disk.

Doesn't matter, its obviously a popular thread ;-)
Can you show us the full hdparm -i for both disks.

Ok, by looking back some pages I see other Seagate drives have ' BuffType=unknown' so you can forget that..

There was at least one other Seagate with similar results to yours,
i.e. very good 'Timing cached reads' and very low 'buffered disk reads'.

So, do you have anything set up in /etc/conf.d/hdparm and do you start hdparm when booting?

I have the following in /etc/conf.d/hdparm:
Code:

hda_args="-m16 -u1 -c3 -d1"
hdb_args="-m16 -u1 -c3 -d1"

and 'hdparm' in default run level as shown with 'rc-status -a'

Just do the following after you have edited /etc/conf.d/hdparm, if you don't have it set yet
Code:
 # rc-update add hdparm default
 * hdparm added to runlevel default
 * rc-update complete.

and see if that helps
mvh

Edit: I just came across this thread where the poster used
Code:
hdparm -i -M -m 1 -d -a -c 3 -u 1 -t -T -X 69 /dev/hdx

on a Seagate like yours with following results
Code:
 Timing buffer-cache reads:   1940 MB in  2.00 seconds = 969.66 MB/sec
 Timing buffered disk reads:  160 MB in  3.02 seconds =  52.97 MB/sec

I use this, to config the driver at bootup (i did the rc-update):
Code:
# cat /etc/conf.d/hdparm
hda_args="-a256A1c1d1m16u1"
cdrom0_args="-d1c1u1

The settings u posted didn't make a difference.
I tried setting the accoustic value manualy but that gave an error.
I also added the W value (not w) and that gave some improved results, but still much too slow.

P.S. notice how u write all the options against each other. also works in the /etc/conf.d/hdparm.

as u can see, my drive has more cylinders than max and less heads.
I know to little about harddrives to tell if these values are hardware related or, software.
My guess is that the number of heads and cylinders are manufactured in.

P.P.S. sorry for the long post.

This is a real puzzle..

Do you have both disks on the same IDE cable?
CD/DVDs on their own IDE cable?
And what chip have you configured in 'IDE chipset support'
Does dmesg show anything interesting about IDE after you boot up, like UDMA(100)?
In fact, why not post it.. and the IDE chipset part of your .config file

mvh

I have the same..
Code:
Configuration:
        Logical         max     current
        cylinders       16383   65535
        heads           16      1
        sectors/track   63      63

Yes, the hdd's are on primary IDE and the cdd's are on the secondary.

Ok thanks for the lists..
one thing I'm not sure of is which chipset your nforce uses. lspci will show it..
The other thing is that you have a lot of chipsets set as <y>.
It would be OK if unnecessary ones were <m>, but I don't think a number of <y> can be a good thing.
My asus p4pe uses the piix chipset.
When you do make any changes, you can set CONFIG_IDE_GENERIC=y to <>. Its for legacy ide and has been known to affect hdparm results & performance.
mvh

Edit: just found this tread http://forums.gentoo.org/viewtopic-t-183857-highlight-a7n8x+ide+chip.html with a bunch of your card's configs and they all had lots of <y> against various chipsets... ;-) ?

i'm trying the settings posted on the link u supplied. I feel kinda stupid not finding that thread.
Here is a snip out if my lspci.
u say it tells me what driver to use, i don't know where to look/read.
Code:
jpc j # lspci -vvs 00:09.0
0000:00:09.0 IDE interface: nVidia Corporation nForce2 IDE (rev a2) (prog-if 8a [Master SecP PriP])
        Subsystem: ASUSTek Computer Inc.: Unknown device 0c11
        Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 6Mhz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- >TAbort- <MAbort- >SERR- <PERR-
        Latency: 0 (750ns min, 250ns max)
        Region 4: I/O ports at f000 [size=16]
        Capabilities: [44] Power Management version 2
                  Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA PME(D0-,D1-,D2-,D3hot-,D3cold-)
                  Status: D0 PME-Enable- DSel=0 DScale=0 PME-
i guess the chipset is nforce2, but i don't see it in the kernel.

At last - if you run 'make xconfig' its easy to see a chipset called 'AMD and nvidia IDE support' or whatever, see http://forums.gentoo.org/viewtopic-t-311867-highlight-nforce2+ide+chipset.html

Thats the one where you particularly need a <y> and I assume its the one that shows up as
Code:
CONFIG_BLK_DEV_AMD74XX=y
which you have selected already.

The big question is whether the others, PIIX, VIA82CXXX, RZ1000, and CMD640 are affecting your performance...
I would suggest changing them to <m> first, and CONFIG_IDE_GENERIC=y to No.

If that doesn't help, it leaves the question of whether your drives are connected correctly, i.e. with the Master on the end of the cable?

Best of luck ;-)
mvh

i always connect drives in that matter, but just in case i checked. and the drives are connected correctly.

i also removed all the drivers except the amd and nvidia one. (the one the thread mentioned) and i still get the same hdparm timings.

a few post back up i posted a snip ou of my dmesg witch said the drive was in UDMA(100). can that be the problem?

Good, at least you are still in business ;-)

I don't think so. my Western Digitals are both UDMA100 and I have buffered disk reads on both around 43.30 MB/sec.
In my case adding PIIX=<y> made a huge difference, and changing my disk cable for one of the latest round ones pushed things up to where they are now. (thats why I'm interested in this post)

I'm afraid it looks as though you are stuck, unless someone else has a brainwave?
Alternatively you could consider investing in something like HighPoint's 'Rocket 133SB' pci adapter to run that disk on..

I'll keep my eyes open

Haven't stopped thinking about your problem.. am currently doing a 'brainstorm' on it with freemind ;-)
Don't suppose you have a spare disk cable to try?
Oh, do the results stay exactly the same if you repeat the -t/T test a number of times in succession?
mvh
Edit What i/o scheduler are you using?
Code:
# cd /sys/block/hdb/queue/
p4pe queue # cat scheduler
noop anticipatory deadline [cfq]

I tried a brand new ATA133 cable, with same results

No, the results vary between 1Mb/s and 10Mb/s most times below 3Mb/s
Cintra wrote:

yep like u, i use the "noop [anticipatory] deadline cfq"

P.S. i tried knoppix3.7, and it gave the same (poor) results.
P.S.S. i tried sisoft-sandra on Wxp, and it gave me a result of 45Mb/s, i don't know if it is comparable, but it clearly states the drive is capable of something more then 3Mb/s.

Oh, the knoppix results are bad news.. however, there is one thing you could try which just might be affecting knoppix as well.
Just above the config option where you set your amd & nvidia chipset there's an option called
Code:
Force enable legacy 2.0.X HOSTS to use DMA

I have come across a number of 'fixes' where turning this off improved poor performance, and one case where turning it on (at the same time as making PIIX = <y>...) gave better performance - it was probably PIIX which improved things as it did for me. So if its <y> try turning it off, and vice versa.

EDIT: I see from your earlier post that it wasn't set then.. :-(

Another thing I wonder about is how full that disk is, i.e. % free space?
Also what filesystems are used on it's various partitions?
Its possible btw to do 'hdparm -tT /dev/hdax' for individual partitions (forget /boot tho').
Btw did you look in /var/log/messages for DMA messages?
And, finally (for now ;-) ) some guys improved results by stopping 'KDED media manager' in KDE Control center > KDE components > service manager. I've turned mine off too because it prints acres of messages if my packet-write disk is unmounted..
Hows that for some ideas :-)
Mvh

Yeah nice list of suggestions, and....
I think we(read you) naled the problem, in fact there was no problem.

i did a:
Code:
hdparm -tT /dev/hda1 (boot-reiser3.6) and got the usual 1.99MB/s
hdparm -tT /dev/hda3 (root-reiser3.6) and got a wonderfull 52.43MB/s
hdparm -tT /dev/hda6 (home-ext3) and got a very nice 40.77MB/s


i can leap with joy, and i feel stupid at the same time, knowing that the whole time there was no problem!

P.S. Cintra, thx alot for your time and effort, although there was nothing to solve, i did learn a lot in the proces, and i thank u for that.
P.P.S if you'r still intrested in my %freespace, i'm more then willing to supply :).

Hey thats fantastic! :-D
Though I think its very strange your /dev/hda results got pulled down so
Another weird problem gets fixed by perseverance... thats the great thing with the tough ones, you learn a lot on the way.
And now I have the beginnings of a great mindmap for this kind of problem in the future
All the best Sade

Thanks so much for this tip! Yeah, i know the post is old but I've gotta acknowledge when someone submits a good tip that was impossible to find on my own! My AZ11E mobo with via chipset would refuse to use dma, until I enabled the HPT36X in the kernel, who knew? EL CHAVO!
