I guess elapsed time. But it doesn't matter, because when I do the test,
emacs uses 100% CPU time.

But emacs can only use one core.

When I do the test, everything is in memory, no disk reading involved.
I have 4GB memory, and the swap area is almost never needed.

You are right, bogomips is perhaps not the only parameter for speed.
Perhaps the CPU cache is also important here.

The speed is acceptable now, with gnus-large-newsgroup = 500, but it
would be interesting to know, why emacs becomes slower after some days
of uptime... ?
Or perhaps I've done something particular, that has made emacs slow?
What could it be...?
