I have been trying to tweak my system a little bit - by using hdparm
command
this is what i did, i have given it step by step - can anybody help me
why my parameters are not getting reflected.
I use RH 6.2 on a celeron 450Mhz
any help will be appreciated.
Shiva
ps.) Thanx for the folks who helped me out of the Internet connectivity
problem.
step 1.)
[root@shiva ~]# hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 5.02 seconds = 25.50 MB/sec
Timing buffered disk reads: 64 MB in 27.20 seconds = 2.35 MB/sec
step 2.)
[root@shiva ~]# hdparm /dev/hda
/dev/hda:
multcount = 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 526/255/63, sectors = 8452080, start = 0
step 3.)
[root@shiva ~]# hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda
/dev/hda:
setting 32-bit I/O support flag to 3
setting multcount to 16
setting unmaskirq to 1 (on)
setting using_dma to 1 (on)
setting xfermode to 66 (UltraDMA mode2)
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
step 4.)
[root@shiva ~]# hdparm /dev/hda
/dev/hda:
multcount = 16 (on)
I/O support = 3 (32-bit w/sync)
unmaskirq = 1 (on)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
geometry = 526/255/63, sectors = 8452080, start = 0
step 5.)
[root@shiva ~]# hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 5.34 seconds = 23.97 MB/sec
Timing buffered disk reads: 64 MB in 33.32 seconds = 1.92 MB/sec
Step 6.)[root@shiva ~]# hdparm /dev/hda
/dev/hda:
multcount = 0 (off)
I/O support = 0 (default 16-bit)
unmaskirq = 0 (off)
using_dma = 0 (off)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 8 (on)
