• Please be aware: Kaspersky Anti-Virus has been deprecated
    With the upgrade to Plesk Obsidian 18.0.64, "Kaspersky Anti-Virus for Servers" will be automatically removed from the servers it is installed on. We recommend that you migrate to Sophos Anti-Virus for Servers.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.
  • We’re working on enhancing the Monitoring feature in Plesk, and we could really use your expertise! If you’re open to sharing your experiences with server and website monitoring or providing feedback, we’d love to have a one-hour online meeting with you.

Plesk-Interface and Domains are very Slow

kraftk

New Pleskian
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.

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
