Rerun the sorted query with &debugQuery=true and look at the module timings.
See what stands out
Are you actually sorting on a "text" field, as opposed to a "string" field?
Of course, it's always possible that maybe you're hitting some odd OOM/GC
condition as a result of Solr growing between releases.

Subject: Sorting by field is slow
In upgrading from Solr 3.6.1 to 4.3.0, our query response time has
increased exponentially. After testing in 4.3.0 it appears the same query
(with 1 matching document) returns after 100 ms without sorting but takes 1
minute when sorting by a text field. I've looked around but haven't yet
found a reason for the degradation. Can someone give me some insight or
point me in the right direction for resolving this? In most cases, I can
change my code to do client-side sorting but I do have a couple of
situations where pagination prevents client-side sorting. Any help would
be greatly appreciated.
Thanks,
Shane
