this is a dump topic!!!

$host_ip = $_SERVER[SERVER_ADDR];
$argyle = fsockopen( $host_ip, 80, $errno, $errstr, 0.01 );

this access server via IP, not via hostname, it will not work on virtualhost-based servers!!!

Hey Peter,

Fantastic guide you've written! You're very good at communicating this rather complicated issue (I think;)

I's administering a small server where I also have my blog. I have the symptoms that you're describing, however I don't get excactly the same error that you mention:
http://munk-nielsen.dk/wp-c...

It says "unable to connect to munk-nielsen.dk:80". This is strange since I'm able to access non-wordpress websites on the server from the server itself (using linux terminal http client: elinks). Therefore, it must be able to resolve its own address, but something still fails.

We recently changed the IP adress of the server and I suspect that I've forgotten to update something somewhere... It's running debian sarge.

Any help would be appreciated!

The time it takes from start to finish for WordPress to build your page, this is just running the PHP code is about 6 secs.
I think this is rather long. It could be several factors:
- The CPU of the host is overloaded.
- One of your plugins is acting up.
- You ran an awfull lot of plugins.

Hi,

My site loads pretty slow and I think it's because it's quite graphic intensive (needs to be for a fashion blog). I have checked my dns and it is not a problem with that (i tried the cron-test) so wondered if you could point me in the direction of what to change on my blog?

I have installed firebug but it hasn't really broken down exactly what is causing the lag (around 8 seconds to load the homepage), and I do not tend to use many plugins on there. Any help would be great on the url that came with this comment.

Thank you for this post. It was helpful in determining whether it was a DNS issue of not and it is not. I just cannot figure out why my personal blog is loading so slowly.

I never get any issue but I found something slow after install wp 2.7 because it's update automatically.

But that's ok for wordpress performance.

Good point, unfortunately in this case the server can do successful DNS queries to any other site not on the server, like cnn.com

I'm having this current problem, my forum (php) works no problem but accessing my blog takes FOREVER to load. I did the cron-test and it came back sucessful therefore it's probably not a DNS problem.

I thought it may be a problem with my theme as I could access the dashboard no problem (which has now decided to load slow as well). But I deactivated the plugins, changed the theme to the default, unpublished all the posts too, and still loading slow.

My hosting provider is having internet problems right now due to a cable breaking in the sea, so he can't do anything right now to help me!

@Jon

I'm sorry Jon, this sometimes happens when I edit a post, the plugin I use to show syntax doesn't do well in the WordPress editor. It's fixed now

Sometimes this happens because the server has been chrooted, and the chroot doesn't have DNS tools. It might help a clueless host to suggest that they try to install the necessary libraries within the chroot so that one can ping a site as the chrooted server user---if a ping works, usually that means domain resolution will too.
