>Subject: [PATCH] Bug 29043: Don't load items unless a patron has been chosen
> on request.pl
>
>This page wraps the item processing into an 'if( $patron )' conditional
>to boost performance before a patron has been located.
>
>To test:
> 1 - Browse to a bib in the staff client
> 2 - Click on the holds tab
> 3 - Note loading time
> 4 - Add 500 items to bib
> 5 - Note loading time - it takes longer
> 6 - Note items are not displayed
> 7 - Apply patch
> 8 - Reload page - is much faster
> 9 - Find/choose a patron
>10 - Confirm items are loaded correctly
