slicehost

I bought a small 256MB slice from slicehost and installed Ubuntu 10.04 64bit and wordpress on it. Performance was dismal as apache was eating up all my memory. Once I did some taming of apache and switched to fCGI things ran fine.

Next I rebuilt as a 32 bit server, and performance was much better.

What benefit would I get from a 64 bit server. Is it all about the memory?

When I pass compiler flag "-mmacosx-version-min=10.5", what does it mean? I think it implies the result binary is x86, not ppc, but is it 32 bits or 64 bits?
