As seen on gplugs:

I have made a couple of speed improvements to the core geeklog files. The modifications are in system/lib-security.php (SEC_getUserGroups and SEC_getUserRights) and public_html/lib-common.php (COM_exportRDF and COM_rdfUpToDateCheck). I welcome any input/evaluation people have about these changes.

More information about these changes, and links to the source, can be found at http://furia.abtech.org.

I updated my site with this and the performance increase was quite dramatic. It only took about 1 minute to do the updates.

Glad it worked for you. -Vinny

Excellent! Works great!

I've recieved a couple of emails recently asking for information about these hacks. They have all been incorporated into Geeklog as of 1.3.7, with some modifications/improvements going into 1.3.8.
