Subject [jira] Commented: (LUCENE-1796) Speed up repeated TokenStream init
Date Mon, 10 Aug 2009 16:00:15 GMT


Mark Miller commented on LUCENE-1796:

Test on the first patch:

Almost brings things back to par with Yoniks short solr indexing test (previous results were
like 90 some seconds):

Before TokenStream revamp:
iter=100000 time=44173 throughput=2263
iter=100000 time=44403 throughput=2252

After TokenStream revamp:
iter=100000 time=46720 throughput=2140
iter=100000 time=47038 throughput=2125

That method inspection was like the second hotest method (see the profiling results), and
this must just take it right out of there.
