Using gnus to create an nndir group of an archive I want to copy to a second nnml server. The directorys look like ~/00 ~/99 ~/98 and contain messages from those years. With file names like so: awk00: 00853 00854 00855 00856 [...] The biggest directory contains some 3000+ messages, the other two have under 2000 each. Making an nndir group of anyone of them causes gnus to go into a spasm of cpu usage that seems clear out of line with the job at hand. Watching top display I see cpu pegged near 99 % and memory around 42%. This lasts for a very long time, like 5 minutes. Just to get to the point where gnus asks how many messages I want to see. Answering with and the cpu usage is pegged again for an even longer time. Eventually the group appears. After sorting date and marking with `M P a' (both seem to take unduly long as well). Then copy to the desired group. The copying is also very very slow. These files have the following format: These two line are the first two headers in every post: #! rnews 1596 Xref: news.demon.co.uk comp.lang.awk:8026 REST OF HEADERS BLANK LINE body body I wondered if the "#!" may be causing all the commotion? I've also tried it with a vanilla emacs and gnus on a dummy account, but still see the hefty cpu usage etc. Seems it must be something about these particular files.
