[Koha-devel] /usr/share/koha/api/v1/app.pl slow to startup

[dcook at prosentient.com.au]

Hi all,

 

Does anyone else notice that /usr/share/koha/api/v1/app.pl is slow to
startup, especially when starting up many instances (for example when
installing/upgrading koha-common)? 

 

I already have a bug open to improve the koha-upgrade-schema performance
(https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=26596) for
package install/upgrade. However with /usr/share/koha/api/v1/app.pl (and
thus "/usr/share/koha/lib/Koha/REST/V1.pm") it seems trickier. 

 

Using --preload-app with Starman might be helpful as it might reduce the
load (by preloading the app into the master process before forking).
However, I think a lot of the work is done by the API startup when it's
merging and validating the API schema. I'm not sure there's really any way
around that. Maybe there are efficiencies to be gained but would need to do
some profiling.

 

Anyway, I suppose I'm just mostly interested to see if other people are also
finding it painfully slow, especially for larger scale installations.
