fwiw I noticed something very like this between 2.2 and 2.4 when 2.4 was new: 2.2 was faster on my Pentium system. I think it was a earlier version of the same chipset.

Here are results on 2.6.7-1-k7:
/dev/hda:
Timing buffered disk reads:  108 MB in  3.02 seconds =  35.78 MB/sec

/dev/hdg:
Timing buffered disk reads:  120 MB in  3.01 seconds =  39.93 MB/sec

Both drives are WD120 Gb (different models), hdg is on an Abit hotrod66 (promise chips).



And how much you would get in 2.4 ?




Sorry.

kowari:~# hdparm -t /dev/hd{a,g}{,}

/dev/hda:
Timing buffered disk reads:  152 MB in  3.02 seconds =  50.33 MB/sec
/dev/hda:
Timing buffered disk reads:  152 MB in  3.02 seconds =  50.33 MB/sec

/dev/hdg:
Timing buffered disk reads:  120 MB in  3.02 seconds =  39.74 MB/sec

/dev/hdg: Timing buffered disk reads: 120 MB in 3.00 seconds = 40.00 MB/sec
kowari:~# uname -r
2.4.26-1-k7
