This is Jessie. That's maybe part of the issue, though. While changing hardware, we also upgraded the OS/apache/mysql. I was kinda hoping for some big gain, but this 1sec delay really stands out.

But following everyone's comments, ll look into 14478, plack... and simply moving everything to 16.05 :)

Any good doc on plack? I got https://wiki.koha-community.org/wiki/Plack, but 5 lines aren't much, not even a clue what <instance> is :)

Thanks everyone!

Philippe,

Are you using Jessie or Wheezy ?

I have seen some interesting performance differences between the versions of DBIx shipped with these Debian versions.

Jessie is much faster.

*Onderwerp:* [Koha-devel] How long is a call to schema() supposed to take
Hello Koha developpers!

I got a question to all the dbix experts out there (I'm not one of them, unfortunatly). I have performance issues in the checkout that remains even after boosting my server's performance with a SSD drive.

In C4/Circulation.pm/*AddIssue*, a lot of transactions take >1s for the call to schema $issue =

Koha::Database->new()->_*schema()*_->resultset('Issue')->create(

This is *3.20*. I specifically isolated that call with timers, I do a bunch of checkouts for the same user, and repetitively, that call take over 1s. The machine is a beast (ram, cpu...), so what should I be doing?

Thanks,
