Well you're not getting that, because doing these variations manually just takes too much time. But I got the following numbers today, when accessing the foreign group nntp+news.eunet.no:no.alt.motorsykler over a 64kb line. The numbers are the value of nntp-nov-gap, followed by the time used by gnus-group-read-group, with an average of 5 tries. The group at this point, had 3 unread articles, and 120 ticked articles. nntp-nov-gap average time used (sec.) 1 20.80 5 21.09 10 33.23 20 55.16 30 63.16 40 74.73 I have no idea of the load on the NNTP server, or the general network traffic at the time of measurement. I guess that a more fair measurement, would involve more averages, with the different values of nntp-nov-gap interleaved. Maybe something for some emacs lisp guru to hack together? - Steinar
