[Koha-devel] Here's a little thing i wrote... kohaprofile

[Heather Braum (NEKLS)]

I'm not a developer, but I lurk on this list anyway. I manage a very large
Koha consortia in Kansas that has faced significant speed issues over the
last year with our system, as some of you may be aware.

I welcome any and all avenues of trying to pinpoint potential speed
bottlenecks in the code! Targeting checkout and checkin processes and code,
especially, for this implementation would be fantastic.

Thanks for pursuing this.
