Unfortunately some APUG custom 3rd party plugins have proven to be extreme problems for the server's performance. These plugins will need to be investigated and likely re-coded. I'll try to have this done as soon as possible.
Plugins that have been temporarily disabled due to issues:
sidebar: latest posts,
sidebar: latest gallery image,
Selective Forum Filter (which lets you hide some forums from view),
random image block on gallery home page,
At this moment the site seems to be really flying. This was the result of some extensive examination into the database activity and removing anything causing huge performance hits. Also, sever key server parameters have been adjusted.
Hopefully the current performance will continue. Thanks for your patience while sorting this out, no fun for all involved.
