Most definitely not complaining just sharing - I read all about the performance improvements and was itching for the longest time to get it done. I simply had no idea the change would be as huge as it was - for me. I mean think about it. I have roughly 33 VM/s per host, each host is 16 CPU (4x4 x 4 hosts) and a good spattering of 2 vCPU in the mix. I was regularly seeing the top 5-8 VMs on each host with %RDY in the range of 3-10% with some spikes for a couple of the 2 vCPUs to over 10% but nothing that was alarming to me. Now I rarely see anything over 1% across the board. Its as if the 'consolidation ratio' has been increased substantially. I know %RDY isn't the only factor to consider for how consolidated you go - but given limitless memory and storage, CPU availability is the only true constraint at that point and Ready Times define CPU availability.
But now the question about how many eggs do I want to put in each basket comes up. I feel like I could double the number of VMs per host and still not see the magic 5% number. But do I really want to put 60 VM's per host? Is management OK with that if the host were to actually go down?
