Relating aslo management, maybe we can ask mozilla folks about it? , would be nice to know how is their setup.

Could someone please approach them? I'd be interested especially in knowing about: * Apache performance tweaks * PHP performance tweaks (opcode caching, etc) * MySQL performance tweaks * ASLO performance tweaks * Why indexes seem to be missing on their schema and how do they cope with it * How many hits they get, and how many machines they have to serve them; so we can make a comparison Feel free to forward this message to the relevant list. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
