I have about 2.8 Gig to copy, and I use to do the copy. While cp is copying from the second hard disk to the first hard disk, I find my system performance drop VERY sharply. X is sloppy, even bash takes many seconds to respond. I using two recent IDE disk (Fudjisu 13 gig, Maxtor 20 Gig), so I'm wondering why the system is so slow? My mobo is a FIC SD11 and I have an athlon 550 Mhz. I tried renicing the process priority to 20, but I don't see any improvement on system usability. Hard disk activity is still frenzy, even if there are other task runnable (X, g++ jobs). Note that I'm running as root when I'm doing the copy. So I'd like to know why the linux kernel can't schedule the task less often? I guess that copying file doesn't eat too many CPU cycles, but is running almost all the time in kernel mode doing I/O... Is there a way to prevent a process from "hogging" the hard disk like that? It's pretty annoying when the system is sluggish like that. Thanks a lot, Laurent Birtz If you wish to reply, I'm not on the list so reply directly to me.. :.˛mkabzwmb˛mbz_^nrzh&zzޗ+^jǫym@Aa0n+d
