Hello all i have a site built on Pligg www.thebookmarks.net and at just 600 uniques per day it seems to be eating all MySQL resources. This is on a dedicated highly optimizaed server with the folks at Unixy.net so i am rather confident that the machine is performing fine, however the site is killing the whole server, does anybody have any suggestions (aside the obvious drop Pligg?) Thx
If you are comfortable with mysql, you could look into tuning - if you can find the offending query(s) you may be able to add an index to improve matters. Another possibility is caching the HTML output, which should circumvent the issue entirely. I'm not sure if Pligg has plugins for that, but Varnish is a popular caching server you could look at.
I have a site using Pligg and it gets hit by spammers thousands of times around the clock. My host has said it's bogging down the shared server it's on. Maybe it's just not showing up in your unique hits? I would recommend tailing the logs to see what kind of activity you have.
