Re: Solaris Performance

For non-postgresql applications, the Suns are
typically faster than the HPs. While direct
comparisons are always dangerous, the SPARC
chips are clocked at about 2-3 times what
the PA-RISC chips are.

The postgresql performance on Solaris is
an order of magnitude (10x) slower than
Linux x86 at same CPU clock speed.
