How strange that you advocate load balancing. Word press does not work properly behind a load balancer, even the WP guys own up to this. wordpress.com uses a different codebase.

Sorry, but you have 22 external Javascript files and 16 CSS background images. Try to use css sprites, css cacheer and maybe phpspeedy to reduce your HTTP requests. You got an F Grade from ySlow. Hmmmm....

Nice info. As always I suggest testing the performance and benchmarking when all is set-up.

nice article, besides the db caching you list, I've found great success using Xcache with PHP5, running on the nginx webserver and multiple fastcgi processes on Debian. I don't get that much traffic, so right now I'm still hosted on a home dsl line - but I have a number of sites all chewing off the same stack.

I used to run varnish as a reverse proxy, but with nginx and it's ability to auto cache images, I've dropped it for now, but I recommend you checkout varnish if you have a busier site.

Oh, and one more thing, I've started to use Flickr as my CDN for images, I only have a couple on there, but I know the more I offload, the less will have to squeeze out via my 2 copper wires! ;)

I've been reading your blog for a while now, and just now made the connection of yours to cari.net. They're my current employer, *cof cof*

Hi there,

I found this rather late, but it saved my page. I struggled getting my wp log working on my rather slow firewall-server-mail-web-thingy. I applied almost all your tweaks and it speaded up my site tremendously. In fact, it stopped my httpd from crashing every time i loaded more than one admin page at the same time. http://wkossen.nl/weblog/ still won't live through a digg frontpage episode though... (it's a alix amd geode 256MB embedded little box with centos 5, so slow by nature..)
In fact, the most effective change was from eAccellerator php plugin. that made THE difference....

Cheers!

Willem Kossen

To turn off all needless apache modules, you will have to go to the /etc/httpd/conf.d/ directory also and rename module files like: squid.conf to squid.off or ssl.conf to ssl.off This way, httpd will not include this modules during startup.

Hi, Do you still recommend Cari.net ? I've heard of several people having problems with them. I am about to switch from my previous hosting company Eapps. BTW I recommend Eapps, but I am switching because I need a dedicated server and Cari.net prices are far more cheap than Eapps... almost 90 times more cheap for what I need.

So, if you were about to switch from another hosting company, would you switch to cari.net?

thanks!

Check out the recently launched WP-Offload plugin. You will see a dramatical speedup especially if your posts have a lot of static content (images, documents, movies, etc.). It will completely redirect all the requests for static content to external cache servers, so the load on your web server will decrease significantly.

This give me a lot of stuff to go over. My site is fine most of the time & some times VERY slow. I am on shared hosting and my site is getting only a few hundred hits a day. I am ready to migrate to my own server.....GRRR headaches.

Another big gain is to switch from Apache/mod_php to nginx+fastcgi.

It's smaller, and more free RAM means a couple extra php processes, should you so desire, plus the inherent speed boost you get from using nginx.

In a (wholly unscientific and useless) benchmark, using nginx with 3 php fastcgi processes, eaccelerator, wp-cache, a properly tuned mysql, etc.

/usr/sbin/ab -n 10000 -c 64 http://host.name/

... gives back ~1500 requests a second at around 525mbit/s total transfer... which puts the limiting factor squarely on my network card.

Nice ideas and tips. You didn't mention moving to CDN service all static content. It provides extra performance (lowers your server load), thus you can serve more web visitors with easy.

That's:

// Enable the WordPress Object Cache:
define('ENABLE_CACHE', true);

It needs quotes around ENABLE_CACHE.

@GrandMaster -- the easiest way which will decrease your server's load most (I assume you;re running Wordpress / similar cms) is to install an edge server / reverse proxy solution.

An easy to follow tutorial regarding this can be read here.

It constantly amazes me how people keep on prescribing the hardest way with minimum return to be done first.
Squid (and other edge server solution) are easy to implement, takes only minutes, and easily drop a double digit server load to a single digit.

Yes, you may not be able to do this on a shared webhosting environment; but so does many of the tips mentioned in this article.

Hope it helps.

Another blog i run has been having severe load issues, and its something i have struggled to understand - i set up the cache and it caches pages but how does it deal with new comments ? Does it recreate the cached pages each time a new comment is posted? I ask becasue i have threads that can generate close to 600 comments in about 5 hours on a particular article _ does any one know where i can find this kind of information ?

Or is the article cached and the comments dynamic or do i need to re do my theme to fit this kind of functionality in
