> Currently there is what seems to be unnecessary synchronization in
> CompoundFileReader. This is solved by cloning the base IndexInput.
> Synchronization in low level IO classes creates lock contention on highly
> multi threaded Lucene installations, so much so that in many cases the CPU
> utilization never reaches the maximum without using something like
> ParallelMultiSearcher.
