Using hdparm -Tt /dev/hdb:

on 2.4:
  Timing buffer-cache reads:   168 MB in  2.01 seconds =  83.58 MB/sec
  Timing buffered disk reads:   44 MB in  3.12 seconds =  14.10 MB/sec
on 2.6:
  Timing buffer-cache reads:   172 MB in  2.02 seconds =  84.95 MB/sec
  Timing buffered disk reads:   34 MB in  3.08 seconds =  11.04 MB/sec

Note the big drop of of 3 MB/sec on disk reads.

dmesg (edited) gives:

on 2.4:
  VP_IDE: VIA vt82c586b (rev 41) IDE UDMA33 controller on pci00:07.1

on 2.6:

  hdb: 80418240 sectors (41174 MB) w/1863KiB Cache, CHS=65535/16/63, 
UDMA(33)

hdparm -i output is identical between the 2 kernels and hdparm settings 
are identical as follows (except cylinders as above):

  Model=IC35L040AVVN07-0, FwRev=VA2OAG0A, SerialNo=VNP210B2RAP0TB

  readahead    =  8 (on)
  geometry     = 79780/16/63, sectors = 80418240, start = 0

I noticed a difference in dmesg:
on 2.4:
  Uniform Multi-Platform E-IDE driver Revision: 7.00beta4-2.4
on 2.6:
  Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2

Could that make a difference?

Please let me know if you'd like me to run more tests, patch kernels, 
..., anything to regain the performance.


Many thanks in advance,

Consider yourself lucky :o)

I had a drop from 55Mb/s to around 35, 2.4.22->2.6.0-test&final.

I think the question should be, what are you fellows doing wrong?

Me too...using a Promise Fastrack 133 TX2 card and a three 80GB Barracuda
drives in a md RAID5 array, throughput dropped from about 40MB/S on the
array to about 30-33MB/S.  Readahead buffer setting make little or no
difference.

I cannot compare 2.4 with 2.6, but I think this is not too much...

It's a nforce2 motherboard, paralel-ATA and Seagate Barracuda IV (or V, 
I cannot remember). AthlonXP-2500+.

Any of the IDE gurus can say something about this?

Thanks!!

Hello:

Any of you knows how to look at this results? They still seems very low 
for me. It's an AMD Athlon 2500+. Hard Disc Seagate Barracuda ATA V. 
Nforce-2 motherboard.

kernel 2.6.0-test11

Any tip? Or is this correct?

Perhaps a dmesg output can provide some commanility with other people 
seeing a loss? Maybe some side by side's of 2.4 performance tests?

Also, you're not nicing any of the tests from 0, right?

Thank you for your suggestion. I tried it but it made no improvement.

I solved the problem in a very strange way. Note that the (b) disk
performance only improves after readahead has been increased on another
(c) drive! (the (c) drive performance was also increased by to 2.4
levels but is not shown here). I could reliably repeat this behavior
after rebooting.

Can any IDE expert explain it?

Looks like a bug. If you don't access hdc, then the read-ahead on hdc 
shouldn't matter. I wonder if the read-ahead code (either the setting or 
the reading) gets the value from the wrong queue or something.

Jens? This could certainly explain some of the confusion about
performance.. Do you see anything strange?

| Looks like a bug. If you don't access hdc,

hdc is / for 2.6, whereas hdb is used for 2.4. So hdc was obviously
accessed prior to this test.

| the reading) gets the value from the wrong queue or something.

Or could this set something in the VIA chipset? I'll take a look in
/proc/ide/via and report if needed.

Let me know if you need more tests to be run.
