Looks like... so far... I win the pissing contest! This is without any tweaks. 
| Code: |
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.46 seconds =278.87 MB/sec
Timing buffered disk reads: 64 MB in 1.43 seconds = 44.69 MB/sec
|
This is with a WD 800JB (I think that's the model number). ATA100, 80GB with 8mb cache. |

I guess I loose the contest with the smallest stream. 
I have tried -X 33 through -X 69, and none seem to work any better.
<beginning of sniplet>
*[root@gk:root] /sbin/hdparm -m 16 -a 1 -c 1 -u 1 -d 1 -X 68 -k 1 /dev/hda
*[root@gk:root] hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 1.01 seconds =126.89 MB/sec
Timing buffered disk reads: 64 MB in 5.39 seconds = 11.88 MB/sec
<end of sniplet>
Time to buy a faster HD i guess. |

[quote="J0rd"]
hey marauder, what kind of drives are those? you got some nice cache speeds[/quote]
sorry for not posting earlier - haven't checked this thread for a while 
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.44 seconds =292.91 MB/sec
Timing buffered disk reads: 64 MB in 1.66 seconds = 38.65 MB/sec
hda is a SeaGate 60 gig 'cuda IV
/dev/hdb:
Timing buffer-cache reads: 128 MB in 0.44 seconds =292.24 MB/sec
Timing buffered disk reads: 64 MB in 2.52 seconds = 25.43 MB/sec
and hdb is an old Quantum LM+ 15 gigger
on an Epox 8kha+ mobo |

Do you get the same figure every time you run it? E.g. my SCSI harddisk always give the following result:
| Code: | hdparm -Tt /dev/sda
/dev/sda:
Timing buffer-cache reads: 128 MB in 0.77 seconds =166.23 MB/sec
Timing buffered disk reads: 64 MB in 2.26 seconds = 28.32 MB/sec
|
While I'd get a wide range of result for "Timing buffer-cache reads" for ide-harddisk. |

well... looks like we've got the same HD! But this is my performance:
| Code: |
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.71 seconds =181.05 MB/sec
Timing buffered disk reads: 64 MB in 1.59 seconds = 40.15 MB/sec
|
how did you get such a fast cache speed?? |

Model=WDC WD200BB 7200rpm BuffSize=2048kB
foxhound root # hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.96 seconds =133.75 MB/sec
Timing buffered disk reads: 64 MB in 1.38 seconds = 46.48 MB/sec
Model=WDC WD200EB 5400rpm BuffSize=2048kB
foxhound root # hdparm -Tt /dev/hdb
/dev/hdb:
Timing buffer-cache reads: 128 MB in 0.93 seconds =137.04 MB/sec
Timing buffered disk reads: 64 MB in 2.21 seconds = 28.91 MB/sec
 The cache speed is .....slow, at least compared with what i've seen above. How can I make it more speedy ?  |

The cache speed is boosted by increasing your CPU's FSB. This is on a P41.8@2.4 (133mhz FSB)... when the FSB is at default of 100 the cache is about 200 (I think ... maybe a little less). At 160Mhz the cache is in excess of 650 ... although my machine is unstable at that speed. |

i added to /etc/conf.d/local.start:
hdparm -u1 -c1 -d1 -m16 -X68 -S120 /dev/hda
I don't get the same values all the time but never under 530 for Timing buffer-cache reads and never under 20 for Timing buffered disk reads

Thought I just had to enter my competitive results(?) without running hdparm at all:
| Code: | root@denice eivinn # hdparm -Tt /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 0.25 seconds =512.00 MB/sec
Timing buffered disk reads: 64 MB in 1.71 seconds = 37.34 MB/sec

This thread is locked pending discussions of how to make it more useful. It may come alive again, and it may get split and parts of it may be moved out of Documentation, Tips & Tricks.
Apparently the discussions broke down. Moved from DT&T, to OTG where "multi-topic" threads usually live out their lives in peace. 2004.DEC --pjp
