[jira] Issue Comment Edited: (LUCENE-1796) Speed up repeated
TokenStream init
[ https://issues.apache.org/jira/browse/LUCENE-1796?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12741393#action_12741393 ]

--------------------------------------------------------------
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.
By the way, I havn't looked if it slows down the single use case at all or not.
