Robert Muir commented on LUCENE-1796:
-------------------------------------

ok lemme restart my benchmark... the performance difference i was seeing with your first patch
so far looked minor, but consistent.

here's some unscientific numbers from your first patch indexing hamshari (about 500MB corpus,
165k docs)
analyzer with no reusableTS() (without patch):
52988 ms
52902 ms
53035 ms
53116 ms
52637 ms

analyzer with no reusableTS() (with patch):
51916 ms
51969 ms
51872 ms
52438 ms
51710 ms
