The problem with 'performance improvements' from a PR standpoint is that
they're not very sexy unless you've got some numbers to go with them.

"8.2 has many performance improvements" - yawn.

"On average, users have seen 40% performance improvements in 8.2, and in
some cases performance increased over 1000%" - wow!

Have you by chance done any performance testing with HEAD that can be
compared to 8.1?
