Only functional test at this point. I'm buliding NUMA awareness to workqueue and planning on doing comparison of before-wq, after-wq, after-wq-with-NUMA-awareness. I don't expect any tangible difference between before-wq and after-wq tho. It would be great if someone can recommend me a test scenario which can emphasize CPU overhead of writeback tasks. Any ideas?
Thanks.
