How much does the machine swap? XEmacs is probably larger than Emacs
20 so the binary might become too large for the machine..
Try M-x elp-instrument-package RET on gnus, nn and mm to find out what
is taking so much time to enter the group -- one from Emacs and one
from XEmacs would be useful for comparison.
