Hi,
Appreciate your update.One thing i can assure is NSX/VCNS is totally out of scope in this discussion.We need to check the performance matrix for the whole vapps.Few things which i can pin-point
1.No:Vm's residing in the vapps?
2.Type of allocation model Org-VDC is using?
3.Boot time for each VM(Easy to find in logs)?
4.Any underlying Storage latency issue?
5.How about if we remove VCD-VC mapping for those VM's and Power-on directly from VC?
So basically we have to do a performance test and check and confirm the results.Then only we can confirm if we really have a performance issue or is this a expected boot time!
