Yes and no. It helps to explore the problem, but I still don't understand... Your CPU is about 1.26 times slower than mine, but your gnus-thread-latest-date is about 62 times faster. That means, that your gnus-thread-latest-date uses about 80 times less CPU cycles than mine ! Now I've tried with nntp+news.gmane.org:gmane.emacs.gnus.general, to see if the back-end matters: nntp is worse, even 0.0052218751s per call. What could be the reason for this slowness? I've used ELP also with the packages "mail" and "message", but there are no slow functions... Further information: All these tests are done with emacs started on June 8, that means 10 days uptime. Now, I've just restarted emacs and the time per call is 0.0002029752s. Much better, but still worse than your result. Why is gnus-thread-latest-date so slow on my system? Why does the slowness depend on the emacs-uptime? TIA for any help, -- Peter
