Can you checkout latest 3.1 branch @ https://svn.apache.org/repos/asf/lucene/dev/branches/lucene_solr_3_1
And test if it solves your issue. There was aproblem in PhraseQuery's internal sorting and quicksort. It does not slowdown over time, but with type of query (how many terms the phrase contains). Maybe you sort your queries according number of terms and so you get a slowdown.
