>Subject: [PATCH] Bug 28172: Optimize Koha::Plugins::GetPlugins
>
>Instead of doing one SQL query for retrieving a list of plugin classes
>(filtered or not by a method name) + one SQL query for each loaded
>plugin (to look up the 'enabled' status), we can do a single SQL query,
>fetching only enabled plugins, and do the method check using `can`.
>
>It allows to use the Module::Load::Conditional cache when requesting
>only enabled modules, which gives a great performance boost
>
>Also, call get_metadata only if needed
>
>Test plan:
>1. Make sure you have some plugins enabled
>2. Apply the 1st patch ("Test script for GetPlugins")
>3. Run the test script several times, copy each result into a file A
>4. Apply the other patch(es)
>5. Run the test script several times, copy each result into another
>   file B
>6. Compare the results. Times in file B should be smaller than in file A
