Long load time for meshes (30s for 50k)
Meshes with 50k take about 30 seconds in debug mode to load. It takes only about 3 seconds in release mode. However, this is a problem because we develop in debug mode. It's difficult to profile because the debugger doesn't get attached while profiling, so the speed in fast when analyzing.
