Lucene IndexSearcher PrefixQuery seach getting really slow after a while

[Jason Wu <Ja...@ihsmarkit.com>]

Hi Team,

We are using lucene 4.8.1 to do some info searches every day for years. However, recently we encounter some performance issues which greatly slow down the lucene search.

After application running for a while, we are facing below issues, which  IndexSearcher PrefixQuery taking much longer time to search:

Our cpu and memory are fine, no leak found:

However, for the exactly same java instance we are running on another box,  for the same info we are searching, it is very fast.

I/O, memory, CPUS are all fine on both boxes.

So, do you know any reasons can cause this performance issue?

Thank you,
J.W
