Plesk-Interface and Domains are very Slow

[kraftk]

Hello,

login to my Plesk-Interface via Web need 1-2 min and clicking on functions need the same time to refresh the Site. Also the Domains are very slow, 10-15 Seconds to show a Wordpress-, Joomla- or other CMS's Homepage. Only a direct Download of a File via web like http://domain.tld/file.zip runs very fast, also ftp-transfers are very fast.
The Server have a good Ping from Internet (12ms), a fat connection (100 Mbit syncron) and nice hardware.

./top in a console show only a bit workload

a "ps aux" looks also good. I think there is maybe a problem with the mysql server or so?! Have anyone a idea what could i also check to find the problem? I use Plesk 11.09 with Ubuntu 12.0.4.

Thanks alot

Kai

Yes, May be your MySQL server is very busy and due to that your plesk panel is loading very slow, Please check your my.cnf configuration and monitor your MySQL process on your server
