Hi and thanks - I've had a play around with both resource and share settings and possibly I'm achieving my aim.
It's only a single ESXi host - nothing complex here. But maybe it is just my interpretation of the performance charts that is getting me confused?
I've gone for the simplest setup which is just the one VM (performing boinc/grid computing) and watching to see it use 100% of the host CPU cycles.
The CPU performance chart says the ESXi host is using 100% of it's MHz, but the CPU listings are all at about 52% - so I've been thinking I had got it running properly. Is this ~50% CPU usage because ESXi knows half of the CPU's are just hyperthreads and if each hyprethread was summed with it's real core (I know that's simplifying it) - then it is actually using 100%?
Thanks
