However, I must warn you all, more interesting = a lot more time to run. These are a lot more complex in that they have real I/O, and they can be a lot more challenging because there are response time requirements (so fairness is an absolute requirement). We are getting a baseline right now and re-running with our user-space VM-to-numa-node placement program, which in the past achieved manual binding performance or just slightly lower. We can then compare to these two solutions. If there's something specific to collect (perhaps you have a lot of stats or data in debugfs, etc) please let me know. -Andrew Theurer > is a broken out and documented > set of patches instead of the monolithic commit you have now.
