Update a post and blam.. every pageload is 20 seconds

Also, all plugins are deactivated, and there’s no ping outgoing (there was, but I removed it and pages still take 20 seconds).

No errors in the Apache error logs. Restarting Apache has no effect. Restarting machine has no effect. Restarting MySQL has no effect, and SHOW FULL PROCESSLIST shows no slow SQL, etc.

Seems even the barebones login page now takes 20 seconds to load. Again, everything else on this host is fast (including PHP).

Exporting then deleting the database, running install.php, and then importing the database again.. and it’s super fast again. All I then do is merely edit a post, click Save, and bam.. it’s 20 seconds for every page again.

Hopefully this is a big clue ??

I’ve erased the whole thing and moved down to 2.1. Same bug. Then I erased it all again and moved down to 2.0. 2.0 doesn’t have the bug. It seems to take exactly 20 seconds to save a post, but then it works and every page loads fast otherwise. So.. it’s a 2.1 problem.

Be helpful to list the exact versions of PHP and MySQL if you can?

Sorry for posting so much but I’m hoping this helps someone who gets the same problem as me..

Further info.. it seems it might be DNS related. I’ve added an entry to /etc/hosts on the server with the server’s hostname and the IP address, and the 20 second wait goes away.

Final update.. I put 2.1 back on again, and it works okay now that the virtual host name I am using resolves from the server in question.

I don’t know why this problem exists more with 2.1 than 2.0, but performing a post update must trigger 2.1 to try and resolve the virtual host’s hostname on every request thereafter.

So.. make sure all your virtual hosts resolve from the server, and not just from your test client ?? Weird bug, but I know someone else will have it sometime!

peter: WordPress tries to make http connections back to itself for the cron process. Adding a post is one of the things that will cause this to be triggered on the next page load. If it cannot resolve its own name, then it cannot connect back to itself to start the cron process.

Useful information, Otto!

It seems then that 2.1 does this on every request, or at least tracks it needs to still do it at next request (if it fails).. whereas 2.0 only does it on posting. ??

Yes, on every request, it checks to see if there are any cron jobs that have had their scheduled time earlier than the current time. If so, it attempts to make that http call to the cron process, which will then run those jobs and remove them from the queue.

Making a post inserts a new job with an immediate expiration time, so that the next hit to the page will cause the job to run.

This post worries me because my ISP has been shutting me down due to excessive cron utilization, stating that something has been running a cron job every two seconds:

I was sent the following as an example:

67.15.211.3 – – [28/Feb/2007:11:13:35 -0600] “GET /blog/wp-cron.php?check=131accfed8363d4c40f4b38b43f9d129 HTTP/1.0” 403 – “-” “-“

Is there any way to view current cron jobs in queue? Is there any way to control this? It looks like, from the above, that the cron job that is being requested isn’t being processed.

Rich.

Just wanted to add that I used this on an Apache server and it seemed to really help out. The pages loaded slow, but it’s not on the fastest connection. This WP install is on a server that I setup myself, and it also runs a couple of Drupal installs as well. Seemed to do the trick for now.

How do I configure it properly for litespeed server?

how to add those hostname and ip address on the etc/hosts form the whm contro panel?
