hdparm decreases performance
I ran hdparm -tT /dev/hda on my system with the following results:
Timing buffer-cache reads: 128 mb 0.89 sec = 143.82 mb/sec
Timing buffered disk reads: 64 mb 1.69 sec = 37.87 mb/sec
After reading a couple post and the man pages I tried the following:
hdparm -X34 -d1 -u1 -m16 -c3 /dev/hda
After running hdparm -tT /dev/hda again I now I get the following:
Timing buffer-cache reads: 128 mb 0.97 sec = 131.96 mb/sec
Timing buffered disk reads: 64 mb 5.30 sec = 12.08 mb/sec
I'm new to the Linux world but this does not seem like an improvement to me. Am I missing something or did I do something wrong?
Thanks in advance for the help.
P.S. - I'm running RH 9.
