MMapDirectory implementation ---------------------------- Key: LUCENENET-425 URL: https://issues.apache.org/jira/browse/LUCENENET-425 Project: Lucene.Net Issue Type: New Feature Affects Versions: Lucene.Net 2.9.4g Reporter: Digy Priority: Trivial Fix For: Lucene.Net 2.9.4g Attachments: MMapDirectory.patch
Since this is not a direct port of MMapDirectory.java, I'll put it under "Support" and implement MMapDirectory as {code} public class MMapDirectory:Lucene.Net.Support.MemoryMappedDirectory:Lucene.Net.Support.MemoryMappedDirectory { } {code} If a Mem-Map can not be created(for ex, if the file is too big to fit in 32 bit address range), it will default to FSDirectory.FSIndexInput In my tests, I didn't see any performance gain in 32bit environment and I consider it as better then nothing. I would be happy if someone could send test results on 64bit platform. DIGY -- This message is automatically generated by JIRA.
