E6600 Is Slower Than P4 2.8G
Sep 2, 2007
i had an p4 2.8g db server, centos4+mysql4.1. the cpu usage went up to 9X% at peak time (web pages loaded within 2~3sec), so i decide to swtich to a new server with a faster cpu. the new box is core 2 duo e6600, centos5+mysql5.0, having same RAM and HD with the old box. surprisingly , the cpu usage keeps above 150% almost all the time, and web pages cost 10+seconds to load at peak time.
how is it possible? what is the problem here? is the cpu, os, or mysql?

Xeon 5310 is using SM X7DVL-E board
E6600 is using SM PDSMI+ board
Both has 2GB RAM with sata raid 1. Will be used with CentOS

I currently have a co-located server with the following specs:
Core 2 Duo E6300
2 GB RAM
2x250 GB HDD Maxtor IDE
and I want to add 4 GB more RAM and replace the hard drives with 4x250 GB HDD SATA, running in a software RAID10.
The main reason for the upgrade is that the server should be able to host a community page (PHP, mySQL) with reasonable performance. I think the use of 6 GB RAM and RAID010 already enhances the capacity of the server, the only thing I'm still not sure about is if I should upgrade the CPU.
The system currently runs a lot of IRC stuff and gameservers. The average CPU usage is around 10% for both cores, in peak times (heavy load on the gameservers), it can jump up to 50-60%.
I have compared servers who provide the backend for community pages and I often see that there is a - compareable slow - CPU built-in (like Dual Xeon 3 GHz with Netburst architecture), but they have a lot of RAM and fast hard drives.
So what do you think? Is a CPU upgrade also necessary (to E6600), or is the additional RAM / RAID already sufficient to run a medium community page flawlessly?

if Web servers might prioritize servicing Regular GET or a Conditional GET.
I have seen busy servers take 9 seconds to respond with a (304 Not modified). On fast networks (LANs), the file size is no issue and, it seems that a (200 OK) with the object is downloaded faster than the (304 Not modified) response alone.
Wiseowl. Not so wise on this one.

I seem to be experiencing slower bw throughput in speedtests on my server today on a domain that is on a shared ip as a virtualhost in apache 2.2.x on fedora core 6.
Right now this domain is pushing somewhere around 35Mbits out and 1Mbit in.
When I d/l from this domain I see pausing and overall performance is roughly 1/2 of what it was yesterday (400K/sec versus ~800K yesterday), when the site was only doing about 3Mbits.
However, another domain on this same server that is not on a shared IP, when I test it, I get my usual 100% d/l speed.
My server is not under heavy load, .02, .06, .00 with 95% idle cpu.
I'm just wondering, should sites with high bw use definitely have their own IP, as shared/virtual hosting is known to cause slowness?

if i use uk2.net's dedicated, will my US users feel slower connection?
if i host my site on uk2.net, will the site load slower for US visitors because the server is in uk ?
what about FDCservers, and serverpronto, any opinions on them ?
uk2.net appeals because of the price.

We used Red Hat with ext2 as our file system on an old server with 100k+ of image files in a single directory. This seemed to preform ok until we switched to FreeBSD using UFS. Now images load very slow. I have read that Ext2 uses and internal hash to speed lookups, while UFS does linear searches for lookups.

I'm making a reasonably uninformed comparison here. Since Windows Vista is noted to be more resource intensive and slower than Win XP, are we right in assuming that Windows 2008 is slower than Windows 2003?
For instance, with two boxes with an identical hardware setup but the two different server OSes, will the same application like, say MySQL run slower on the Win 2008 machine?

I have currently a server with a "Intel Core 2 duo e6640 2.4Ghz".
Now the company I'm at moving to a new data center and offering me a box for the same price with a Intel P3.4.
As I understand I would move from a two core to a single core CPU.
In the first move letter they send me, they where saying I would get a CPU plus, plus 1 GB mem more.
