Hi all,
I made a non-trivial performance change in mail-archive. Not sure how big the impact will be. Cheers, Jeff =============================== PROBLEM: The message backlog at mail-archive is at a 60,000 message backlog. This is producing multi-day archiving delays for many lists. CHANGE: I implemented "poor man's windowing" as discussed two years ago at http://www.mail-archive.com/[email protected]/msg00901.html The MAXSIZE resource is set to 3000 and I commented out three lines in delmsg in mhamain.pl (containing &file_remove, &dir_remove, &file_remove operations) USER IMPACT: Users will only be able to see ten index pages (thread or chonological) and if you want to see older messages, you will have to use the search engine. I suspect this is what users do anyway. BENEFITS: Vast speed in MHonArc for large lists. Message filing time drops from multiple minutes for the huge lists to a capped maximum of about 15 seconds. Vast reduction in MHonArc memory requirements for large lists. This may allow more efficient disk caching, again speeding up the service efficiency. Minor disk savings from reduced sizes of .mhonarc.db files. UNKOWN: I believe this change will not negatively affect the References Follow-up behaviour, but will double check with the MHonArc folks. _______________________________________________ Gossip mailing list [EMAIL PROTECTED] http://jab.org/cgi-bin/mailman/listinfo/gossip
