We also had issues with 4.2, though I really don't remember the details. Some simple queries such as 'q=ubuntu' would take tens of seconds whereas on 4.1 it was almost instantaneous. In fact, even in 4.3 I feel that things have slowed down terribly (3000 ms on simple queries whereas 4.1 would do it in tens or maximum a few hundred). Of course, the index is constantly growing so that may be a factor. Note that in both cases the index and configuration was carryover from 4.1 so that may have been an issue. Moving back from 4.2 to 4.1 I bit the bullet and deleted the extant documents.
