Here are the profiles. I went about as follows:
- Start up emacs2[12],
- load elp.el,
- M-x set-varialbe RET elp-sort-by-function RET elp-sort-by-average-time RET,
- start up gnus,
- M-x elp-instrument-package RET gnus RET,
- enter folder,
- M-x elp-results.

Note that there are no delays due to disk access as all data had been
in cache already.

Hope that helps.
