--- Comment #13 from Ere Maijala <[email protected]> --- Some benchmarking results: My test system is intentionally memory-constrained, items are included and OAI-PMH:MaxCount = 1000. All values are measured from 100 requests starting at offset 190341 when doing a full harvesting without date limits. The database contains 0.97 million biblios and 2.4 million items. Reported times are averages with standard deviation in parentheses. Full duration of oai.pl: 12.98s (0.94s) Biblionumber query: 0.0024s (0.0024s) Fetch+create record: 6.84s (0.51s) Creating response: 4.97s (0.50s) As far as I can see, this represents the full harvesting run pretty well, so it doesn't slow down anymore when getting to higher biblionumbers. As the results indicate, query duration for a set of results is now pretty much meaningless. We spend most of the time collecting the record metadata and creating a DOM for it, and then writing the actual response, which is part of the HTTP::OAI module. So to sum it up: with these changes the biblionumber query is no longer a bottleneck. Previously, it easily took 15 to 20 seconds on my test system. -- You are receiving this mail because: You are watching all bug changes. _______________________________________________ Koha-bugs mailing list [email protected] https://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-bugs website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/
