Hi,
The hard disk at my office which is 8GB seems to give better performance compared
to my home hard disk 17GB ?
As Shridhar pointed out his hdparm tests give the following output.
Timing buffer-cache reads: = around 130MB/sec
Timing buffered disk reads: = 20 MB/sec
On my office hard disk it is around the same as above after doing
hdparm -a1 -c1 -d1 /dev/hda
On my home PC with 17GB seagate Hard disk I have compiled DMA support into the kernel
( kernel 2.4 ) and I do hdparm -a1 -c1 /dev/hda during startup. But I get the following
test results which are very low. :
debian:~# hdparm -tT /dev/hda
/dev/hda:
Timing buffer-cache reads: 128 MB in 2.09 seconds = 61.24 MB/sec
Timing buffered disk reads: 64 MB in 13.38 seconds = 4.78 MB/sec
------------------------------------------------
debian:~# hdparm /dev/hda
/dev/hda:
multcount = 0 (off)
I/O support = 1 (32-bit)
unmaskirq = 0 (off)
using_dma = 1 (on)
keepsettings = 0 (off)
nowerr = 0 (off)
readonly = 0 (off)
readahead = 1 (on)
geometry = 2096/255/63, sectors = 33683328, start = 0
debian:~#
------------------------------------------------
Can anybody point out what could be the reason for this and what I can do to increase
the
performance of my Hard Disk. I am on Debian.
Thanks in advance.
Regards
