Just wondering if the Postgres hackers have done any performance measurements on Postgres compiled with GCC 3.x against Postgres compiled with GCC 4.0. I'm wondering whether or not the auto- vectorization stuff in 4.0 provides any performance improvements to Postgres 8.0.x.
Offhand I'd not expect auto-vectorization to be much help for Postgres,
but you never know till you try ...
While cruising the vast and global interweb I found myself here
http://gnu.ghks.de/software/gcc/projects/tree-ssa/vectorization.html
and while that's a bit over my head I gathered that GCC 4.0 would provide "more better" performance.
