Well I don't see any benchmark numbers in the original patch.  Just an

The regression was in a Ken's commercial database benchmark. I couldn't
reproduce it but presumably it did fix it otherwise Ken would would have
piped up?

I'm more inclined to revert it and not add the sysctl (ugh) until we have a
good reason to do so.


If you revert this then Ken's database benchmark gets worse. Hence the
sysctl.
