Hi Yonik. > Do you see any requests that took a really long time to finish?
The requests that take a long time to finish are just simple queries. And the same queries run at a later time come back much faster. Our logs contain 99% inserts and 1% queries. We are constantly adding documents to the index at a rate of 10,000 per minute, so the logs show mostly that. > Start with the thread dump. > I bet it's multiple queries piling up around some > synchronization points in lucene (sometimes caused by > multiple threads generating the same big filter that isn't > yet cached). What would be my next steps after that? I'm not sure I'd understand enough from the dump to make heads-or-tails of it. Can I share that here?
