Hi, Even though I have 64bit hardware I always install the 32bit version of Linux.  I do so because of the past discussions on this list that made me believe the 32bit OS was better because 64bit caching is actually slower due to the requirement that the cache be filled to a certain point before it is moved.  I think I recall something about the amount of RAM having some effect here also. Using a 32bit version over a 64bit version seems counter intuitive, however that is what I have taken away from these conversations about 32bit vs 64bit Linux. I'm using CentOS 6.x on a LAMP server that gets a low amount of traffic.   However I may make the jump to Linux on my desktop this summer. (this will be my 3rd attempt to become M$ free except one VM so I can use IE for testing) I think all of my hardware is 64bit.   So that begs the question, is 32bit better than 64bit or do I not understand the issue? Thank you for your feedback. Keith ------------------------ Keith Smith
