Performance Fixes #1375

Closed poojanilangekar closed 6 years ago

poojanilangekar commented 6 years ago

This PR fixes two of our performance bottlenecks.

  1. Modify the tile_group_locator_ to use CuckooMap because it is faster for lookups.
  2. Modify the ReadWriteSet to use tbb::concurrent_unordered_map because it is faster for iterations.
