Hi everyone,
Okay, I still have a strange problem. I just copied 97 mb in a test folder on two systems. One is a Pentium III 750 laptop with a 10 gig 5400 rpm hard disk. The other is my new Pentium 4 2.66 GHz desktop with a 7200 rpm ultra-ATA 100 hard disk.
I found the file transfer time is almost the same on both systems! Worse, it seems that while it only takes about 20% of my CPU's capacity to copy the files on the P3 750, on the P4 2.66 GHz it took all but 6% of the system resources. Any ideas why there would be such a dramatic impact copying the same 97 megs of data?
Is it the location of the files on the drive perhaps? On my new system my Linux partition starts 40 GB into the drive and is 60 GB in size. On my laptop there is one big Linux partition covering all 10 GB. Could this cause such a major performance impact?
Both systems, I should add, are running Mandrake 9.0. The only difference in config as far as the distro goes are the various drivers (i.e. different sound cards, ATI Radeon drivers on the desktop, etc.) and the fact that the desktop is running KDE 3.1 RC1 during the tests whereas the laptop has 3.0.2. Actually, since I first wrote this message, I just tested again in IceWM, and the results come out the same. ack!!!
This is rather disappointing to say the least!
Thanks,
Tim
You might be limited by DMA being disabled. Install hdparm and, as root, do hdparm -tT /dev/hda or b, whichever ide drive you test. I use hdparm -c3d1 /dev/hda hdparm -c3d1 /dev/hdb at the bottom of /etc/rc.local. There is a good howto here:
