Zero fills in fullBlockLighting #45

Closed foxostro closed 12 years ago

foxostro commented 12 years ago

Startup time is slow largely because of a large number of zero-fills under fullBlockLighting. (and maybe other places too)

Investigate possible improvements to reduce this cost, such as reducing the amount of memory used for lighting data.

About 7% of zero-fills during the "warming up" phase at app launch are under addVertex, under the call to alloc. This and fullBlockLighting are the places where the most zero-fills occur.

I wonder whether the zero-fill cost at app launch can be reduced by pre-allocating memory for GSChunkVoxelData objects in a memory pool. This will at least help ensure these objects are packed contiguously in memory.

Moot point now. Closing.
