Обсуждение: 8.2 -> 8.3 performance numbers

Sorry for the cross-post, but this is performance and advocacy
related...

Has anyone benchmarked HEAD against 8.2? I'd like some numbers to use
in my OSCon lightning talk. Numbers for both with and without HOT
would be even better (I know we've got HOT-specific benchmarks, but I
want complete 8.2 -> 8.3 numbers).

We've done it on TPCE, which is a hard benchmark for PostgreSQL.  On
that it's +9% without HOT and +13% with HOT.  I think SpecJ would show a
greater difference, but we're still focussed on benchmarks we can
publish (i.e. 8.2.4) right now.

Bleh, that's not a very impressive number.

Anyone else have something better?

Are there any industry standard benchmarks that you know of which
PostgreSQL excels at?
