Hi Fridolin, I assume that's only 1 Plack instance on that 1 machine though, yes?

We added a nightly reboot (made by logrotate) of starman for security. Page processing goes from 2 seconds without plack to 100-200ms with it, not the search pages of course because they depend on Zebra request time. We use 2 or 4 workers on a 4 CPU machine. We used 8 workers on a 4 CPU machine once for a library with a lot of accesses. Regards, Le 08/02/2018 à 23:41, David Cook a écrit :
Jonathan,
It is certainly slower than I would like.
The Plack support in Koha wasn’t great last time I tried it. I’m curious to try it again now, since people have worked on it more. I have used Plack for non-Koha apps and it’s worked great, so I’d like to move away from CGI.
I’m planning to use Plack for dedicated servers, but for larger multitenant deployments, I’m wary of the resources that Starman would require when aggregated all together. While higher performance would be great, it certainly comes at the cost of resources. But… I haven’t tried that out recently, so I’m keen to see what the actual memory requirements will be.

David,
I cannot imagine Koha without Plack, it must be so slow... unless you run very old versions.
The wiki page is there since years and the psgi in our codebase as well (the one outside the debian directory). Did you only try once to read the wiki page, modify the apache config and run starman or plackup with the psgi file?
Before the debian package was ready for Plack, I was doing that (since at least 2014).
You really should compare the performance with and without Plack...

I've been avoiding Plack because we don't use Debian, but at some point I'll have to use it, and it would be great if it was community supported beyond just Debian. I'm happy to help test things, so long as I can have some guidance on what to do.
(I'd love for the multi-tenant management tools to be de-debianized as well, but totally recognize that money/time is an obstacle. It's something I'd like to look at more in the future myself, but occupied with non-Koha projects at the moment...)

Are they really in sync ? They look very different (I cannot use the rest api with misc/plack/koha.psgi for instance).
IMO a good starting point would be to move debian/templates/plack.psgi outside of debian/ and make it the .psgi reference file for all types of install (and remove misc/plack in the process). Any thoughts ?

Good point, Julian. You are right.
Basically, we ship misc/plack/* which we keep in sync with debian/templates/plack.psgi.
I would love to spend some time de-debianizing hte multi-tenant management tools, but its been hard to find sponsorship or time for it. Most people are comfortable with Debian it seems.

What about people that do not use Debian ? It seems that there is no "standard" way to use Plack outside of the Debian world, and it looks like 90% of https://wiki.koha-community.org/wiki/Plack is outdated. If we abandon CGI support, I think we should first provide a clear setup documentation. I would happily rewrite the wiki page, but I'm not sure of what to write (how to setup Plack on dev install for instance, or 'standard' install without debian packages). Or maybe I'm missing some important up-to-date documentation about Plack ?
