Hi, We have a Quad-Core Intel Xeon Processor and I was wondering if it's makes sense to install the 64bit version CentOS 5.1. - Are all applications for production webservers able to run on 64bit processors? - Is there a noticeable gain in speed on a 64 against a 386 kernel? - What advantages are there with using a 64bit rather than a 32bit processor in the hosting industry? They have a fairly large database so I'm wondering if the 64bit has any noticeable advantages in that area. Thanks!
