There may be minor differences, but I would not expect this much difference. Actually, further testing has shown that the write performance on the second machine varies anywhere from 20MB/Sec to 54MB/Sec depending on when I test it. Unfortunately, it appears random from my point of view. I'm still running tests to try to find a cause or at least a related symptom. The First system has Maxtor 7V250F0 drives (250GB). The second system has Seagate ST3500641AS drives (320GB). They are both 7200RPM SATA II drives with 16MB cache and NCQ support. -- Bowie

3Ware 9550SX-4LP Performance
by Kirk Bocek 16 Oct '06

16 Oct '06

I know there are a few 3Ware fans here and I was hoping to find some help. I just built a new server using a 3Ware 9550SX-4LP with four disks in raid 5. The array is fully initialized but I'm not getting the write performance I was hoping for -- only 40 to 45MB/Sec. 3Ware's site advertises 300MB/Sec writes using 8 disks on the PCI Express version of this card (the 9580 I think.) I'm guessing 4x PCI Express has more bandwidth but 133Mhz 64-bit PCI-X is no slouch. The only two things I need to change are to put the disks in 3GB/Sec SATA mode (they're in 1.5GB/Sec mode right now) and to enable memory interleaving on the motherboard (I only have two sticks of memory, this M/B needs 4 for interleaving.) But I don't think these things should drop me down to the write performance of a single IDE disk. Does anyone have any suggestions on improving write performance? The Details (I know the devil is in here somewhere): Supermicro X7DVL-E Motherboard Dual Xeon 5130 (2 Ghz) 2GB RAM 3Ware 9550SX-4LP in a 133Mhz 64-bit slot. 4x Seagate ST3400620AS 400GB SATA Drives NCQ Enabled but currently in 1.5GB/Sec mode CentOS 4.4, Kernel 2.6.9-42.0.2.ELsmp Stock Kernel 3Ware Driver 2.26.04.010 Bonnie++ 1.03a 50GB Benchmark run four times on an ext3 filesystem: ------Sequential Output------ --Sequential Input- --Random- -Per Chr- --Block-- -Rewrite- -Per Chr- --Block-- --Seeks-- Machine Size K/sec %CP K/sec %CP K/sec %CP K/sec %CP K/sec %CP /sec %CP Beryl 50G:64k 44572 77 53084 14 40624 7 47790 72 162504 12 96.5 0 Beryl 50G:64k 45960 79 53068 14 39972 7 47701 73 162510 12 96.8 0 Beryl 50G:64k 36846 64 37579 10 36785 6 48090 72 162609 12 96.9 0 Beryl 50G:64k 45205 77 53621 15 40757 7 48325 73 162331 12 96.4 0 ------Sequential Create------ --------Random Create-------- -Create-- --Read--- -Delete-- -Create-- --Read--- -Delete-- files:max:min /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP /sec %CP Beryl 16 3928 99 +++++ +++ +++++ +++ 3961 98 +++++ +++ 12442 99 Beryl 16 3929 98 +++++ +++ +++++ +++ 3957 99 +++++ +++ 12373 100 Beryl 16 3718 94 +++++ +++ +++++ +++ 3389 84 +++++ +++ 12307 99 Beryl 16 3920 98 +++++ +++ +++++ +++ 3969 99 +++++ +++ 12421 99

I can try that, but when I tested on the first server, I found that disabling NCQ increased the read performance by 10M/s and decreased the write performance by 10M/s. Maybe I'll get different results from the Seagate drives. -- Bowie

Uneven CPU speed with CentOS 4.4 on a Mac Pro
by Michael Lampe 16 Oct '06

16 Oct '06

Hi list, I've recently managed to install CentOS 4.4 on an Apple Mac Pro. Functionality-wise everything works great, but when trying to benchmark the system, I don't get stable runtimes, they differ by more than 30%. For example a benchmark run with our PDE solving code takes between 500 and 800 s on the completely unloaded machine. Suspicious kernel output (complete output attached): PCI: Probing PCI hardware (bus 00) PCI: 0000:00:03.0: class 600 doesn't match header type 01. Ignoring class. PCI: 0000:00:05.0: class 600 doesn't match header type 01. Ignoring class. PCI: 0000:00:06.0: class 600 doesn't match header type 01. Ignoring class. PCI: 0000:00:07.0: class 600 doesn't match header type 01. Ignoring class. and quite a bunch of APIC error on CPUx: 60(60). This is probably due to Apple's not quite perfect BIOS emulation code. According to /proc/cpuinfo the CPUs don't support any power managment, cpuspeed isn't running or even configured, and they are always shown as 2.66 GHz, which is correct.

tg3: eth0: No interrupt was generated using MSI, switching to INTx mode.
by Andreas Micklei 16 Oct '06

16 Oct '06

Hi, I just installed CentOS 4.4 x86_64 on our new 2 x Dual Core Opteron Server. First the system was unstable, but I after turning of Power-now it runs stable (anyone else experienced this?). However the following line in dmesg puzzles me: tg3: eth0: No interrupt was generated using MSI, switching to INTx mode. Please report this failure to the PCI maintainer and include system chipset information. Has someone else experienced this? What does it mean and who am I supposed to contact? Sorry if this is a stupid question, but a simple pointer would be appreciated. Apart from this message the system runs fine. Hardware Information: Server: Supermicro 816S-R700 Motherboard: Supermicro H8DSP-8 Chipset: ServerWorks HT2000 / HT1000 Processors: 2 x Opteron Dualcore 2.2 GHz RAM: 4 GB Ethernet is of course on the mainboard. I have already upgraded the tg3 driver with the latest version from Broadcom, but the line in dmesg still appears. regards, Andreas Micklei

Latest kernel fixes AMD cool 'n quiet
by Centos Admin 16 Oct '06

16 Oct '06

Just thought I'd follow up on my post from around august.... it seems that the latest kernel has indeed fixed the cool 'n quiet issues with my Athlon X2 3800. basically the following messages were appearing; powernow-k8: ignoring illegal change in lo freq table-2 to 0x2 powernow-k8: transition frequency failed and both cores were going at full 2.0ghz speed. Now with 2.6.9-42.0.3.ELsmp the errors have disappeared and both cores are running at 1ghz when the system is idle. I'm very surprised as I checked the changelog (rpm -q --changelog) and there was no specific mention of any fix that I could find. I had actually toyed with the idea of running another distro on the server as it lives in my garage which, obviously, has no Aircon and the summers here in Brisbane get pretty hot.

'Political' Questions on CentOS please
by Tom Brown 16 Oct '06

16 Oct '06

Hi I have used CentOS personally for 'ages' but i have some questions that i need answering from the wider audience. These are for management as i am proposing RHEL for our QA and Prd infrastructure and CentOS for dev. I would go CentOS for all areas but we need 'support' on our prd systems. Can anyone tell me roughly how many cpu's are running centos? How widespread is it, does anyone really know? How many developers are helping with CentOS? When did CentOS 'start' and how long will it be around for? I am trying to get an accurate answer to fend off the 'well it could disappear at any minute' argument. thanks guys
