From 04cc9de8f2fbcb11f133c88f02fc11504b3ea6f3 Mon Sep 17 00:00:00 2001 From: Perttu Ahola Date: Sat, 15 Apr 2017 10:55:52 +0300 Subject: MeshUpdateQueue: Add a MapBlock cache that minimizes the amount of MapBlock copying done in the main thread Cache size is configurable by the meshgen_block_cache_size (default 20 MB). New profiler stats: - MeshUpdateQueue MapBlock cache hit % - MeshUpdateQueue MapBlock cache size kB Removes one type of stutter that was seen on the client when received MapBlocks were being handled. (the "MeshMakeData::fill" stutter) Kind of related to at least #5239 Originally preceded by these commits, now includes them: - Move the mesh generator thread into src/mesh_generator_thread.{cpp,h} - mesh_generator_thread.cpp: Update code style - MeshUpdateThread: Modify interface to house a different implementation: Actual functionality will be changed by next commits. - MeshMakeData: Add fillBlockData() interface (so that caller can fill in stuff from eg. a MapBlock cache) --- builtin/settingtypes.txt | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'builtin') diff --git a/builtin/settingtypes.txt b/builtin/settingtypes.txt index 2c74d6c44..5dc48c00e 100644 --- a/builtin/settingtypes.txt +++ b/builtin/settingtypes.txt @@ -551,6 +551,11 @@ enable_mesh_cache (Mesh cache) bool false # down the rate of mesh updates, thus reducing jitter on slower clients. mesh_generation_interval (Mapblock mesh generation delay) int 0 0 50 +# Size of the MapBlock cache of the mesh generator.
