[xwiki-users] Tuning xwiki for low memory webhosting service.

Hi, I have been using xwiki on my hosting service for a few weeks now but i am getting permgen errors (My memory allocation is 64Mb Max permgen, 128Mb Max Heap). Quite a few of the problems seem to be happening when web bots are trolling the site. Essentially i just want to display the information on the page without the show/print bar at the top and the comment/attachment/history/info tabs at th bottom so that these links arent visible at all to the web bots, as some arent reading robots.txt. Would it be best you just make a new skin? and show the bar using a velicity template? or is there a way in the permissions or config to block the show/print bar & comment/attachment/history/info for guests? regards, rob. xwiki.robmunro.net
