Alright. Im making a minigame with the new 1.9 command blocks (they are pretty powerful). And as i am expanding the game more and more. Me and the testers are noticing a good amount of delay (personaly i dont really call it lag) for a short while now. And im suspecting the amount of command blocks(especialy the blue repeater ones) to be the cause.

The point is:the server isnt really showing a need of ram. I have never hosted a public server. So maybe theres something i dont know to increase server power besides ram. But its only using ~10-20% of 2gb it has currently allowcated. Increasing it to 4gb has no noticable effect

The second thing i have been noticing (but are quite rare) is weird redstone behavior.

For example: lets say you remove a life of the player if hes standing at its spawn point and then teleport them away, using the new chain command blocks. So it should only happen once

What actually happens is that it removes 30-40 lifes, and then teleport them away. Even through its a chain command block

I also want to note the server is spitting out a lot of "server cant keep up. Did system time change?" Messages
