[vlo 3.0 beta] Long lists take long to build

Description
Opening a long list of facet values, e.g., the full list of subjects with no search term given, takes very long time. And, alas, after selecting one item in there, there is no way back to list but to build it slowly again.
Tested with Firefox 28.0 on Ubuntu 14.04 LTS.

I will investigate. Paging and/or defaulting to 'only show values occurring more than 2 times' could mitigate this.

Replying to twan.goosen@…:
Added paging in r5123 which greatly reduces the waiting time.
Merged to 3.0 branch in r5124
Will close after investigation of behaviour in fully loaded testing environment
The performance is very acceptable now IMHO. (see http://catalog-clarin.esc.rzg.mpg.de/vlo/search). Closing as fixed.
Note: See
TracTickets for help on using
tickets.
Maybe a good handling of the long subject list (ca. 38000 entries, ca. 24000 of them unique!) is to
display a question like:
38000 different facet values found. Loading and displaying them may take a long time. Display all values? yes/no (clickable).
BTW: The list is a heavy load in VLO 2.18, too, but at least there it is persistent and not only living in some hovering JavaScript? object.
