Re: [CentOS] OT: 4 dual cores agains 2 quad cores

I'll take a stab at it, but I'm only hypothesizing (aka no proof). I would think the quad duals would be faster because of it being easier to dissipate the heat (should be less per chip). However, if you get a really industrial strength liquid cooling system for the two quad's then they'll pro

Hi people, Do you have pointers to web documents that help me make comparisons between buying a server with two quad core 2.33 ghz or buying a 4 dual core 2ghz server? I am trying to answer a question of performance. It is not important the redundancy/failover or the price of the server. Just the p

[CentOS] Zimbra vs. Scalix vs. et. al.

Well, I stumbled onto zimbra I have a Scallix system built, but still have some rough edges to try to smooth. Like the way it works with sendmail, no dnsbl's will work as sendmail sees all mail as coming from locohost (scalix). Still battling that one which is when I ran across Zimbra. S

Re: [CentOS] Very slow disk performance on CentOS 4.5 [solved]

Well most desktop motherboards these days provide for 2 SATA devices and 2 emulated PATA devices. Though the emulated PATA devices will probably end up using PIO instead of DMA for transfers which is slow and processor intensive, so these are usually reserved for optical drives, which are slow.

Yes, I was going to say this too, make sure the SATA settings in the BIOS are all set to SATA operation and not "legacy", then you should see /dev/sda and /dev/sdb and all DMA, IO size, NCQ and multiple sector settings will be properly negotiated at start-up. I bit the bullet and rebooted my

Another route you can go is getting a PCI/PCIe/PCI-X BBU RAM/NVRAM card to put an external journal on to speed up fsync performance for filesystems like ext3 over software raid since these cards can go beyond 1GB of memory unlike hardware raid cards that usually max out at 256MB. What are

You can use the powerfull install command in your modprobe.conf. Putting forcedeth in /etc/modprobe.d/blacklist and forcing it install in modprobe.conf after e1000 via a install command could be a solution. I never tested or tried this, I dont know if it will work. Try to setup HWADDR first. Thei
