- Client leverages block chunk short pool
- Client doesn't load physics on entities by default
- Block chunk disk map writes files without allocating a buffer
- Increase memory limit 6GB->8GB
- Server block chunk disk map writes directly to output stream instead of inbetween buffer
Increase human move speed
LOD components re-attach physics
