Hi All,
First off I fear that I may be sending people
up the wrong tree by giving "dump" data as my
evidence of the computer being slow. I am using
dump data only because I can get reals numbers.
This gets me around having to use weasel
words like "perceived". EVERYTHING is slow.
Also, the other individual reporting the slow down
is not using an LSI card. He is using two 3ware9508
Raid Controllers.
Did some test from my install CD/DVD's in "rescue mode" on
Computer C. 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" CentOS5 install DVD in rescue mode:
transfer rate 4422 KB/s, estimated finish 4:10
"dump" CentOS4.4 (2.6.9-42.EL) install CD in rescue mode:
transfer rate 8468 KB/s, estimated finish 2:09
I also got a "dmesg" from computer B, as requested by Sumant.
Computer B: VXA-3, CentOS 4.5 , SATA-150-4
-T
[fresh boot] "dmesg" from Computer B (CentOS 4.5):
