Thread: Intel C++ Compiler

Hi,

does anyone has made experiences compiling postgresql with
the Intel C++ Compiler for Linux to improve performance?
I've read an article in the german magazine "IX", where speed-
ups more than 40% are possible, only by re-compiling the code.
We are running postgres on a Dual-PIII/933 NetServer which
works like a charm - but fast is never fast enough ;-)

I have not heard of anyone trying but would be interested in seeing the
numbers.  I don't think databases in general would have a dramatic
speedup.

Compiling C code with a C++ compiler might be the first problem you would
run into.  But since the PostgreSQL server is I/O-bound in almost all
situations I think it wouldn't make much of a difference anyway.
