For example, a partner with ~250k auto_renew issues is taking about 9 hours to run. If we run that same number of holds in 5 parallel chunks ( splitting the number of issues as evenly as possible, it could take under 2 hours. Test Plan: 0) Install the Perl library Parallel::ForkManager 1) Generate a number of issues marked for auto_renew 2) Run the automatic_renewals.pl, use the `time` utility to track how much time it took to run 3) Set parallel_loops to 10 in auto_renew_cronjob section of config in koha-conf 4) Repeat step 2, note the improvement in speed 5) Experiment with other values -- You are receiving this mail because: You are watching all bug changes.
