Optimize chunk replication #8

Open temportalflux opened 2 years ago

temportalflux commented 2 years ago

Replicating chunks is taking a HUGE amount of time (probably because of chunk data serialization). Try to optimize this, but if there are no significant gains or straightforward paths, the replicator system should process in a separate thread.

Serializing the replicate world packet for a given chunk can take up to 5ms per chunk.

The "Game Development In Rust" discord had some good discussion around this topic a couple days ago. Saving these screenshots here as a note on how to optimize sending chunks over the network when users join.

Moving this ticket out of investigation and updating its name.

2 optimizations:

We should serialize as little data as possible
Replicating the world should be done on a thread so the main thread of the integrated client or dedicated server doesn't hitch
