Yes, I've tried increasing it to 2048, 3528, and higher with latest
unmodified mixfs, while saturating load and having 3-4 concurrent
writers.  At 3528 and more, performance seems to drop (but would need
more testing), but latency starts to get high.  2048 improves
performance to similar levels as the patch, but the patch seems to
help slightly more.  It's harder to tell, I'm not sure how to test
this in a reproducible manner.
