Subject Slowness on Java 11 with Lucene 6
Date Mon, 29 Jul 2019 15:17:26 GMT

We have noticed slower response times on search with Lucene 6 when upgrading to Java 11.

We use the version 6.6.5 of Lucene. Our servers are on Windows, with SSD devices. Our index
contains several millions of documents.
When upgrading from Java 8 to Java 11, we have noticed slower response times in query searches
: sometimes 30% slower, sometimes twice as slow, depending on the server capacity.

We measure response times with 200000 queries.
We have made our tests with different JDK providers. We have noticed the same deviation.

Have you encountered this problem ?
