Without further information we can't help here. So we would need the type of queries (conjunction, disjunction, phrase,...). There are significant changes which may cause some queries to be slower, but others like 50 times faster if the exact number of results are not needed, see https://www.el

Noticed performance degrade from lucene-7.5.0 to lucene-8.0.0

Hi All, I have recently updated from lucene-7.5.0 to lucene-8.0.0. But I noticed considerable performance degrade. Queries that used to be executed in 18 to 24 milliseconds now taking 74 to 110 milliseconds. Any suggestion please? Regards, Khurram
