Server architecture

Thread for a client

• Heavy load thread: Thread to get file, access to mysql, load the map, return to the sender the data done by the query, all where it can be blocked lot of time
• Thread to read and parse on the network packet
• broad cast thread: all broad cast object interconnected, complexity: O(n), where n is all player, broadcast too the player disconnection and send it to map management thread
• map management thread: local map management object interconnected, complexity: O(n) for local player, but in normal case O(n^2) for all players see the other player, where n is local player
• ...

Visibility

For now it's just calculated on the local map.

But after, each player will have near clients near him self. Send the move to it. this list is updated frenquently and not at each move parsed (mainly to fast the move parsing).

Start procedure

• send protocol
• login
• sync the file for the datapack
• inventory
• monster
• play

Benchmark

Single benchmark

Is used to profile specific code. Not implemented for now into catchchallenger, but can be useful to test and develop the visibility algorithm.

General benchmark

Is used to profile the normal usage, with step, chat usage, and all used into the normal play.

Implemented into catchchallenger. Useful to know the general memory usage, ... But have few variety of action do (only step for now).
