Re: [gentoo-amd64] Recommendations for Intel Xeon
Hi! I'm getting a server with Intel Xeon CPUs that support EM64T (Intel's version of AMD64). Would you recommend sticking with i686 compile options for a production-level server? Depends on software you plan to use. 1. If you need binary only packages (like java), it is better to stick with i686 (because such software is often optimized specially for AMD 64 bit cpus not for generic x86_64) 2. Check portage for AMD64 support for all important packages if some packages miss support - stick with i686 In other words: if you plan to use only common open source software (like apache, samba) - use AMD64, otherwise stick with i868.

Would you recommend sticking with i686 compile options for a production-level server? What are the benefits of compiling with 64-bit support? Is the speed difference (if any) worth the potential loss of stability? From what I've heard, Intel's x86_64 CPUs really are just x86 with added 64-bit emulation on the chip. 64-bit code therefore runs slower, etc... Might want to confirm it from someone who actually has one, though. -- Luke-Jr Developer, Utopios http://utopios.org/ -- gentoo-amd64@gentoo.org mailing list
