I will try to do some changes to the VarHandle code over the weekend. Maybe we can imporve it. To me it is completely strange that we see an improvement here. I have one guess: Maybe when we completely revert the optimization for MMapDirectory's MemorySegmentIndexInput and the other, the performance will go straight upwards. I have the feeling that we had the slowdown because of the GC pressure and now we have improved and are at the "bad perf" level of #15104. If we would didable the MMapDir/NIOFSDir/ByteBuffers dir optimization completely it could be that Mike's benchamrk gets much faster! ...just guesses.... but this is my only explanation for what we see here! -- This is an automated message from the Apache Git Service.
