The problem is probably that Fossil is computing SHA1 checksums on all the files in the check-out to see if they have changed. You can get Fossil to use mtimes instead by doing: fossil setting mtime-changes on Mtime-changes is now the default, but I'm guessing you are using an older version of Fossil. After you turn mtime-changes on, you have to do a check-out before it takes full effect, I think, but after that things should go faster. Check-ins and check-outs will still be kind of slow in as much as Fossil still computes MD5 checksums over everything in those cases. See http://www.fossil-scm.org/fossil/doc/tip/www/selfcheck.wiki for an explanation of why we do this expensive computation. If you find things are still too slow, let me know. We can work together to profile your runs and try to figure out what the inefficiency is and fix it. > > -- > Joshua Paine > LetterBlock: Web applications built with joy > http://letterblock.com/ > 301-576-1920 > > _______________________________________________ > fossil-users mailing list > fossil-users@lists.fossil-scm.org > http://lists.fossil-scm.org:8080/cgi-bin/mailman/listinfo/fossil-users D.
