Shawn, yes, there is 56 VM access every second, and for each VM access, the scheduler will invoke filter for each host, that means, for each VM access, the filter function will be invoked 10k times. So 56 * 10k = 560k, yes, half of 1M, but still big number.
I'm fairly new to openstack so I may have missed earlier discussions, but has anyone looked at building a scheduler filter that would use database queries over sets of hosts rather rather than looping over each host and doing the logic in python? Seems like that would be a lot more efficient...
