-- [ Picked text/plain from multipart/alternative ] Your'e missing the point still a bit, with ht you don't have 100% global cpu to play with in the first place, you only have 50% plus the benefit of ht. The o.s essentially doesn't realise 2 of the cpu's are virtual and can't be used to their full extent, it still thinks you have 4 full cpu's. This bears our roughly with the load figures top right. Personally we try to keep all of our dual cpu machines under a load of 2 (not one has gone over in the last week), but there's a fair bit of slack in that and can go higher, just we prefer not to for performance reasons.
I wouldn't ideally want to see double that (whilst things like webservers would probably be ok with higher loads as less noticable) on that box, let alone triple, but depends what kind of performance and contention people are ok with really.
