Subject: [PATCH] Optimize packet used to unload chunks for the client
2013-01-18 19:27:42 +08:00
At the moment telling a client to unload a chunk involves calling the entire chunk from memory, deflating it and then sending it through the pipes even though the client ignores it and based on the bitmap simply unloads the chunk, and to add the cherry on top, this is done on the main server thread.
