Solved Using Vault (CraftConomy) causing lag

Hello.

I have scanned my server and it has been found that Chest shop and my plugin cause most laggs when they withdraw or deposite money.

PlayerInteractEvent (Chestshop, buy event/ hold right mouse button):
Total duration: 21677.697 ms / 12000 ticks
Average duration: 1.806 ms/tick

TransactionEvent (Chestshop):
Total duration: 20933.21 ms / 12000 ticks
Average duration: 1.744 ms/tick

EntityDeathEvent (my plugin, withdraw money if you kill monsters)
Total duration: 13304.375 ms / 12000 ticks

Average duration: 1.109 ms/tick

I have the newest Version of Vault & Craftconomy.

Does anyone have an idea how I can solve this problem?
