Hi The CPU usage goes upto 100% during search. We were using RAM Directory, but later switched to MMap Directory.
The CPU usage remains between 90-100%. Is it obvious that the CPU usage remain high during Lucene search or we are missing something? Our data set was only 3.5 Million records (~ 2 GB index size). We reduced our data set to 25000, still CPU usage was very high. There are no update operations, only searching. We are running basic Lucene queries. Regards Rajnish
