[xwiki-users] Your experience about storage requirements and performance of customized Xwiki solutions

Hello, I'm thinking abut another custom solution based on xwiki. Though I'm worried about storage consumption and performance if there will be >10k objects with ~10 string attributes. My experience with quite small solutions (few hundreds of objects http://odo.lv/Recipes/Recipes1_en and http://www.ante.lv/xwiki/bin/view/Arts.Songs/ ) required using of apache cache. I know that http://l10n.xwiki.org/xwiki/bin/view/L10N/ is quite slow, but don't know why. Can you share your experience/recommendations, how to build it in the right way? Thanks in advance, Valdis
