Hi All, I met a strange situation that the Lucene.Net used only 1 processor on a quad dual-core processors machine when the search load exceeded a certain threshold (i.e., 35 searches per second). It took a few minutes before the load got distributed over all processors. When the load was below the threshold (i.e., 20 searches per second), all processors got used evenly.
The used Lucene.net is v2.9 and the index size is about 4GB with 15 millions of documents. There was no index update and the load was search only without any index update. Has anyone seen this kind of behavior before? Thanks a lot, Frank
