Re: Strange IDE performance change in 2.6.1-rc1 (again)
From: Tobias Diedrich
Date: Fri Jan 02 2004 - 22:35:51 EST
Here are some numbers I got on 2.4 and 2.6 with hdparm.
2.4.23-acl-preempt-lowlatency:
0: 47.18 47.18
8: 47.18 47.18
16: 47.18 47.18
32: 47.18 47.18
64: 47.18 47.02
128: 47.18 47.18
2.6.0:
0: 28.68 28.73
8: 28.87 28.76
16: 28.82 28.83
256: 43.77 44.13
512: 24.86 24.86
1024: 26.49
Note: The last number is missing because I used hdparm -a${x}t and it
seems that it sets the readahead _after_ the measurements and I
had to compensate for that, after I noticed it with the following
measurement.
2.6.0 with preempt enabled, now 3 repeats and
hdparm -a${x}t /dev/hda
instead of
hdparm -a${x}tT /dev/hda
0: 28.09 28.11 28.17
128: 41.52 41.44 40.94
256: 41.07 41.39 41.32
512: 24.59 25.04 24.84
1024: 26.49 26.30
2.6.1-rc1 without preempt and corrected script to do the readahead
setting first, anticipatory scheduler:
0: 28.92 28.91 28.49
128: 33.78 33.60 33.62
256: 33.62 33.55 33.60
512: 33.54 33.54 33.41
1024: 33.60 33.60 33.43
2.6.1-rc1, noop scheduler:
0: 28.36 28.86 28.82
128: 33.45 33.50 33.52
256: 33.45 33.51 33.52
512: 33.23 33.51 33.51
1024: 33.52 33.54 33.54
Very interesting tidbit:
with 2.6.1-rc1 and "dd if=/dev/hda of=/dev/null" I get stable 28 MB/s,
but with "cat < /dev/hda > /dev/null" I get 48 MB/s according to "vmstat
5".
oprofile report for 2.6.0, the second run IIRC:
CPU: Athlon, speed 1477.56 MHz (estimated)
Counted CPU_CLK_UNHALTED events (Cycles outside of halt state) with a unit mask of 0x00 (No unit mask) count 738778
