Don't be silly. A performance improvement is a performance improvement. According to your logic, using assembly-optimized locking primitives shouldn't be done unless we've exhausted every possible optimization in every other part of the system (a process which will likely never be finished). If the optimization was for some obscure UNIX variant and/or an obscure processor, I would agree that it wouldn't be worth the bother. But given that (a) Linux on IA32 is likely our most popular platform [1] (b) In theory, this will help performance where we need it most, IMHO (high-end systems using large shared buffers) I think it's at least worth implementing -- if it doesn't provide a noticeable performance improvement, then we don't need to merge it. Cheers, Neil [1] It's worth noting that the huge tlb patch currently works in IA64, SPARC, and may well be ported to additional architectures in the future. -- Neil Conway <[EMAIL PROTECTED]> || PGP Key ID: DB3C29FC ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
