Difference Enterprise vs SMP

montyw · 07-07-2004, 01:29 PM

I have FEDORA 1 and LILO menu gives me Enterprise and SMP and "reglular Linux" and other selections. I have an ABIT IC7-G MAX2 mobo w/P4 2.8C(Hyperthreading). It looks like 2 cpus to windows XP pro. ! Why would I use enterprise over SMP?

If you have a hyperthread capable CPU, use SMP.

If an authoritative answer from a complete stranger doesn't sway you, do some benchmarking for yourself. Timing a kernel compile while booted under the different kernels should be instructive.

I'm going to guess that the enterprise kernel has 64GB memory support. However, you'll want to use the 4GB kernel (smp) if you don't have more than 4GB since there is a performance hit for the larger memory kernel (there's also compatibility issues with some 3rd party apps with any 64GB kernels).

SLES (and even consumer SUSE Pro) provides the 4GB-smp and 64GB-smp kernels and have been doing so for many, many years now. I'm just guessing at what RHELAS's "ent" kernel is.

Thanks for the info on Enterprise vs SMP kernel. Since I have "only" 1024KB of DDR RAM, I can sefely use SMP kernel and eliminate the selection for the Enterprise kernel & its entries in /boot directory. Enough performance hits have come my way already with WINDOWS XP!
Thanks to all for the help.

First off, thanks to the posters who answered the question. I have to admit I wondered about that myself.

Secondly, FYI the original forum this was posted in is for questions relating to business use of Linux. I know it's confusing, but topics related to home/hobby use of distributions that have "Enterprise" in the title, or questions about the "enterprise" kernel don't belong in the Linux - Enterprise forum.

I've decided to move this to the Newbie forum since it's likely that other new users may have this same question.
