[Dump-users] slowwwwwww

2.6.18-8.1.8.el5

Hi All,

After I wiped my hard drives clean of CentOS 4.4
(RHEL 4.4 clone) and installed CentOS 5 (RHEL 5),
I noticed that everything was slower.  Especially,
dump, which was 3.5 times slower.

So, I did some tests from my install CD/DVD's in "rescue mode"
and the System Rescue CD from http://www.sysresccd.org.
I used the same backup script (dump) that I use in normal
boot mode. I stopped the backup after dump gave the first
estimate of time:

    "dump" CentOS4.4 (Kernel 2.6.9-42.EL) install CD in rescue mode:
         transfer rate 8468 KB/s, estimated finish 2:09

    "dump" CentOS5 (Kernel 2.6.18) install DVD in rescue mode:
         transfer rate 4422 KB/s, estimated finish 4:10

    "dump" System Rescue CD (Kernel 2.6.22.9):
         transfer rate 4370 KB/s, estimated finish 4:15

Has anyone else seen this?  If so, were you able to fix it?
