Ok, here are profile report - from the profile I see that you run the new
scalable sampling branch.
It will be interesting to compare this with profile of master
code.
Looking at the profiles we can see that there is no much to
optimize. A profile with 100 or 200 vms would be more
interesting when yappi is fixed to cope with this concurrency
level.
