Please don't drop the cc lists. There are others who probably have more informed opinions than I do who won't get to comment if they don't see it.

Hi All,

If you all would not mind a post from the general
public Linux user, after doing a complete disk wipe of CentOS 4 and installing CentOS5, my system is preceived to be 3 times slower.

Quoted 8 lines

To troubleshooting this, I made a post on CentOS's
bugzilla: http://bugs.centos.org/view.php?id=2382

Would some of the experts on this group mind
looking at the bug to evaluate the possibility that it is being caused by the underlying scsi
driver? The post contains a dmesg from "Computer C".
(Yes, I am getting a bit desperate.)

There's still too little information in the bug report to tell much of anything. The dmesg doesn't indicate any anomaly with the megaraid (although the LSI people might be able to tell better). However, it also doesn't contain a trace of the tape drive.

Quoted 4 lines

Best guess would be a slow down in the megaraid driver. Can you try doing a speed test on it? (hdparm -t should suffice).

James

Hi James,

The other guy reporting the problem

http://www.centos.org/modules/newbb/viewtopic.php?topic_id=10659&start=0#forumpost34209
is not using a MegaRAID card. He is using 3ware9508 Raid Controllers. He is also using a different processor (amd vs xeon) and a different chipset (Intel Greenwood vs nVidia)

I also spoke to Neela Kolli (Mega RAID maintainer) and he said he'd never heard of the problem. Here are some tests (including dhparm) that I sent to Neela (he never wrote back).

I have also checked with Stellen over at the "dump" list and he has not seen the problem (yet).

The problem occurs when backing up to a two different types of tape drives and to an eSata drive.

When I am running a "dump" on computer C, gnome-system-monitor shows my two cores running at only about 10 to 20% and switching back and forth (one at 0% the other at 20% for about 5 seconds, then switching positions)

On Computer C (Cent OS 5), when typing in Word Pro (a windows word processor) in Parallels, I can watch myself type. Computer B (CentOS 4.4, now 4.5) has the same version of Parallels
installed on it (Parallels-2.2.2112-lin.i386) that computer C
(CentOS 5) has. The perceived speed difference is about a factor
of three (you can not watch yourself type).

All the "Low Level" test I run seem to come out the same between Cent OS 4.4 and 5. Very frustrating! It is almost like some system monitor component is looking at everything and slowing things down. If this was Windows, I'd go straight to the Anti Virus as the culprit. (Does SE Linux do such things?)

Are there any performance tests I can run for you?

Thank you for letting me ramble, this problem is really frustrating. I am afraid to any additional CentOS5 server out there and CentOS 4.x is so terribly out of date.

I think this is beginning to point to problems with dump. What are the corresponding figures for dump under 2.6.9 (or are the two sets of figures centos5 followed by centos4)?

James

Computer C:

Note: 3.6 times slower

Hi James,

The above shows the dump speed difference between CentOS 4.4 and
CentOS 5.

Quoted 6 lines

I suspected dump at first, until I noticed everything else
was about 3 times slower too, such as Parallels, etc. Open Office 2.3 (linux version) opens about 3 times slower.

Are there any tests you know of to shake out who is
slowing the works down?

Yes, could you do backup write tests without dump in the process (as in just do a straight dd from /dev/zero to the devices in centos 4 and 5). If there's no difference in that, it's some scheduling or filesystem issue with dump, I'd expect.

When I get a chance, I am going to run a dump from my
CentOS 5 install DVD in rescue mode (linux rescue). This to make sure no high level driver is slowing things down. I will let you know what shows up.

James

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
