To your other question we're still trying to come up with numbers, the system has many things going on and showing something 100% attributable to this is hard - I'm trying to see if we can get a more exact A/B test.

madvise() doesn't help ensure there's less dirty data in the system, which is different from what you are describing. If the write-queue becomes too long, then anything else that needs to write now has to wait... which doesn't work well with a database load. Now mysql sync's and has to wait for a half-gig of data to be flushed. That's a problem.
