Description

Deepamehta uses Way to much ressources. While working (only one user!), it constantly uses up half a cpu-core (Intel Xeon 2,4Ghz), peaking in 100% load 2 cores in some cases. I haven't monitored the used ressource-usage with multiple users working at same time, I will report the results of this measurement soon.

Maybe caching in RAM would speed up stuff. The Machine now uses around 2GB out of 16GB, having a minial Debian install and doing nothing else then hosting DM.

Monitored Machine:

Virtualized (vSphere)
4 Xeon 2,4Ghz cores (I think Gulftowns, but not sure)
16Gig Ram

Some Additional Infos:

Usage is nearly zero before logging in. After Login one core goes up to 100% for some seconds.

Performance Issues seem really be ACL related, as stated in release e-mail.
