Server Problem RPR Justice

I am under the impression that since about 2 weeks server performance has gone down. I see more "stuttering" and lag with the more crowded maps like "stealth of sand" and "Delivery 2", like the memory is getting full or something like that. Less crowded maps seems to perform normal. Does anyone else experience this too?

When the site is full, plenty of players and map required lots of muscle to perform,
then it gets annoying. Less servers, one or two, should help.

I turned off the Private server since we don't really use it much.
