-----------------------------------
Summary: CloseableThreadLocal maybePurge could be too expensive
Key: LUCENE-4474
URL: https://issues.apache.org/jira/browse/LUCENE-4474
Project: Lucene - Core
Issue Type: Task
Reporter: Robert Muir
Was doing some tests with geonames database (19 fields, just using
StandardAnalyzer), and noticed this in the profiler.
It could be a ghost, but we should investigate anyway.
It seems ridiculous for a situation like mine:
* indexing with one thread
* every 40 Analyzer.tokenStream() calls [basically every other doc], this thing
is called
* it gets iterators over the map, checks threads, this and that. but of course
there is only one thread!
Maybe its a good idea if it checks size() first or something. at least dont do
this stuff if size() == 1, as I bet a lot of people index with a single thread.
Or maybe all this stuff is really cheap and its just a ghost.
