Re: [Koha] Anyone have an annual circulation of over 10 million transactions
Although 10 million transactions are an absurdly large circulation, I wonder if by "transactions" you mean db transactions, including that is workload incurred by OPAC users, remote searches, administrative work etc.? If on the other hand you do know of a library that does have such a workload/production, I would be most curious to know of the software (ILMS/DB/OS), architecture and hardware used.

If so, could you please reply with library name and number of circs. Thanks.

Salvete!

Mebbe for a small rural Library in the West, but it wouldn't surprise me if someone in the East at an Academic or large Public saw those sort of stats. Cheers, Brooke

To be clear, the figure I cited for SCLS is for circulation only, with 12 million items being borrowed by patrons. There are of course many more db transactions taking place, with a proportionally high number of searches and (one hopes) all of those items also being returned. Plus cataloging, records maintenance, reports, etc. Math clarification: some of the earlier discussion cited circs per second, but that's going one step too far. Also, the 8 hours assumption isn't quite right. Many of our larger sites are open 10-12 hours per day. Also, because of the public web interface and the addition of a TALKINGtech i-tiva telephony interface, patron self-service renewals can take place 24/7. So, rounded off a bit... 12 million issues and renewals in 2012 / 365 days / 24 hours / 60 minutes ------------ average 23 circs per minute Of course the really interesting question is about peak load, not average. Based on reports of circulation by time of day, our busiest hour is Monday afternoon, 16:00-17:00. In that time slot our peak load averages to 77 cpm, or 1.28 per second. Large? Yes. Absurd? Not yet... but we're still growing. =) -- Greg Barniskis, Computer Systems Integrator South Central Library System (SCLS) <gregb at scls.lib.wi.us>, (608) 242-4716
Thank you to all who replied to my query. Yes, I was referring to an annual circulation statistic (checkouts to patrons) at a large library or a consortia group of libraries of around 10 million. SCLS seems to have hit the mark. Thank you.
