I remember the times (not that far away) when paging through the result of a query
in the emacs interface resulted in a lock of several seconds after each <PGDOWN> or
<DOWN> keypress, even in medium sized queries of 1000 queries. This went away in the
meantime.

I just found the issue that caused the lag in the vim interface:

Using query.count_messages instead of query.search_messages.count did the trick.
