Hi Philippe,
I run quite a few Koha instances, so I feel your pain. A couple months ago I opened https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=34477 but I haven’t dedicated any time to work on it yet (and I have no plans to work on it anytime soon). The ORM eats up a lot of memory, and if I recall correctly C4::Context also requires a fair bit of memory. I don’t think you’ll really be able to hack this one per se as there are quite a few changes that are needed. That said… I suppose you could always create an alternative background jobs worker and use that instead. If I recall correctly, I don’t think you use the RabbitMQ, so you could exclude lots of code. In theory Koha::Database->dbh() should provide a database handle with a smaller memory footprint, but I haven’t tested it. But yeah… I think you’d basically need to do a rewrite.

I'm trying to run a server with MANY koha instances (for educational purposes), but although the usage is very small, the resources required just make everything explode. background_jobs_worker.pl for instance uses 170M per instance, and plack uses 200M without anything being loaded. Any suggestion how this could be hacked (locally) to allow for 200 koha instances on a machine without requiring 100G of memory ? The object model seems at fault here, but I see no way to go around <useKoha::BackgroundJobs;> "use Koha::BackgroundJobs;" at the top of the script.
