Strange server optimization questions

[johnburk]

I have noticed a strange problem on a server. When sending an email in horde there is a 10 second delay after you press send. When feeds need to be fetched, there is a 10 second delay.

I have checked apache logs, mysql error logs, mysql slow query logs and cannot find any problems.

I am not sure if this is a cpanel, mysql, apache or other problem. I just have no clue. It seems to be related to mysql/php.

I cannot find a server with the same problem. It is not the website software, that has been tested, it has something to do with the server settings, I just have no clue what.

Has anyone had a similar problem or heard of a similar problem? Can this have something to do with apache/php/mysql settings?

What does this portion here mean:

When feeds need to be fetched, there is a 10 second delay.

Do you mean RSS feeds on sites for some kind of software application? Please be more specific. Also, if you could post a link to one of the feeds for us to check it out.

Any feed, for example that of cPanel. But most importantly when pressing send in Horde or when logging in using anything that uses php/mysql, there is an initial 6 to 10 sec delay.

Here is a screenshot. After the first time, the whole page is cached for 4 hours so other users do not experiance the same.
