I've seen the upper limits for the largesmp kernel in the RHEL4 U3 release notes (https://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/release-no tes/as-amd64/RELEASE-NOTES-U3-x86_64-en.html). However, I'm wondering if anyone can point to the lower limit recommendations for the largesmp kernel. At what point (memory and cpu) does the largesmp kernel provide better performance than the regular smp kernel. This is on x86_64 (not x86). Installing RHEL4.6 x86 seems to use the hugemem kernel on this BL680c G5, while RHEL4.6 x86_64 uses the largesmp kernel. I'm wondering specifically for x86_64.
