[Koha-devel] Koha Load Testing
Fellow Kohackers, Do any of you have a favour script or suite of scripts (or even a method) for doing load testing against a Koha installation? I know there are some scripts available in misc/load_testing, but my understanding is they aren't terribly useful or current. Is that correct? Something that can throw a user-configured amount of punishment at a Koha server, then report on the results, would be ideal. The output should include both the user perspective (response times) and what's happening on the machine (memory/CPU usage, query times, etc) in the context of the machine's specifications. If all this data can be compiled for various configurations, I think we'd have the makings of a fine, evidence-based Koha Tuning Guide. Thanks, all! -Ian -- Ian Walls Lead Development Specialist ByWater Solutions ALA Booth 732 Phone # (888) 900-8944 http://bywatersolutions.com ian.wa...@bywatersolutions.com Twitter: @sekjal ___ Koha-devel mailing list Koha-devel@lists.koha-community.org http://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-devel website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/

I know there are some scripts available in misc/load_testing, but my understanding is they aren't terribly useful or current. Is that correct? quite. I did use ab and siege. But siege is my favourite. The nice thing with siege is that you can input a url file that will do the search with all the url provided. I used a TransferLog from apache, (One or two days) edited to suit the siege format for input and that was VERY useful for load testing. http://opac.distant/cgi-bin/koha/opac-search.pl?idx=q=l%27explosion+de+la+communication provides that kind of output ** SIEGE 2.70 ** Preparing 30 concurrent users for battle. The server is now under siege...^C Lifting the server siege.. done. Transactions:450 hits Availability: 100.0 % Elapsed time: 64.00 secs Data transferred: 2.82 MB Response time: 4.25 secs Transaction rate: 7.03 trans/sec Throughput: 0.04 MB/sec Concurrency: 29.92 Successful transactions: 31806 Failed transactions: 0 Longest transaction:7.37 Shortest transaction: 0.00 The nice thing is that you can use -v to see which elements have errors.

The output should include both the user perspective (response times) and what's happening on the machine (memory/CPU usage, query times, etc) in the context of the machine's specifications. Having both in one software would not be possible unless you have a client and server script to do that... But then ... it could be like an auditer having some interests in the place. But I may be mislead. You can use munin or nagios to inspect the server while load testing. If all this data can be compiled for various configurations, I think we'd have the makings of a fine, evidence-based Koha Tuning Guide. We already have bits in the koha-devel list for that. We would need to compile those bits into an administration/setup guide though on the wiki. #idea Hope that helps. -- Henri-Damien LAURENT BibLibre ___ Koha-devel mailing list Koha-devel@lists.koha-community.org http://lists.koha-community.org/cgi-bin/mailman/listinfo/koha-devel website : http://www.koha-community.org/ git : http://git.koha-community.org/ bugs : http://bugs.koha-community.org/

I created the wiki page... go for it!

Please see my notes para 2. a) at http://aandc.org/koha/. (This page also contains other questions - if anyone has the time and patience to assist.)
