Development Assistance Performance improvement

Hi guys,
I wrote a plugin, which sets a wool lane under the player, if he moves. So, 3 woolblocks in front of the player and 3 woolblocks behind the player and 3 directly under the player will be set with different colors dependent on yaw. Also all Woolblocks above, directly in front of the player and directly behind the player will be set to air. In the end, all woolblocks, set as path will be removed after 5 seconds.

My pc-server (offline) does not come afterwards with setting and removing blocks by one player and I want to ask you, if you have any ideas, to make this not so performance heavy
Thank you, Paul
