The new board is fast

Everything feels pretty snappy after the relocation. Cool.

Yes, it's better than the old one!

Thanks Krilli for helping me set up the new Linux server!

Yes, the pages load almost instantly now, even from half way around the world!
Firebug is a great tool for checking and optimizing web sites for speed:

I have not used Firebug much but will sure take a look. Unfortunately there is not much I can do in terms of the internals and performance except maybe a few optimizations.

Some hardware facts:

Old server: Dual AMD 3GHz, 2MB RAM, ADSL 28Mb/s in 1Mb/s out, Win2003 Server IIS, mySQL

New server: Quad AMD 3.2GHz, 4MB RAM, DSL 4MB/s both ways, Linux-Apache, mySQL

Having both web server and mySQL running on the old dual core machine it seems it hits bottlenecks, while with quad cores there is always at least one core available. But then, previously I had two Win2003 dual core servers, one running the SQL, the other with IIS, and performance was not better. So it may also be Linux/Apache is simply more effcient. Also the 4Mb/s outgoing line speed is an improvement. It's also a higher priority line than my previous "home" connection.

Another nice feature is that the new server runs with variable CPU speed on demand. The CPU cores are running at 25% speed only most of the time, but speed up to 100% when needed. This gives a dramatic increase in energy efficiency and decrease in dissipated heat.

Something has happened to the website. Firebug shows the forum.php page is taking 15 seconds to load.
Not all php pages are slow, but forum posts and searchs all take 15 seconds to load.
I suspect it may be related to the 404 checking code which was recently implemented.
I saw one page with the 404.js code taking 15 seconds to load.

Private messages also take 15 seconds to load - almost like some kind of script is running, but can't complete, and it finally times out and displays the page.

I have seen this and have been asking at the vB support. The weird thing is that the whole page is renderd including the closing html tag and then there is a log delay.... It seems to be a bug in the version I installed yesterday.

Basiclally I have done all repairs / rebuilds and even reboot, but it does not seem to help. And the CPU and SQL are doing just about nothing....

I do not think so because that is simlpy a .htaccess redirect to a regular page.
For example try this one which is quite fast: http://www.41hz.com/forums/content.asp
I will have to delete that one soon, so it does not ruin my stats..

Any Apache & php wizz out there who can help me debug?
