then sorry.. my answer is useless to you. since I can get in taking 1 second... or 90. no pattern to it at all.. comparing it to the 'majority' of site is also useless since they do not have the varible factor this site has.
(the varible speed has nothing to do with users online - there can be 2000+ on and a page take 1 second to load or 900 users and take 90+ seconds. Time of Day has no effect ethier.)
