Custom scripts - give me tips about reduce server spam

[DiBi]

I'm writing my own scripts for heroics/raids.

Just found in ogre patch notes these words:

"Actor.Effect[Vile Build up] (or whatever it's called) STOP USING IT. Using Effect names spams the servers and causes them to lag. It's only a matter of time before they pull the logs and find __ toons sending thousands of these commands every second"

Never thought getting info about actor effects (that should already be on client, no?) would cause that. It is always a request to server? No excuses? Particular cases?

Also when it becomes a problem? In my scripts I do a loop with 50 ms thread sleep and on only one account (it sends commands via uplink to others), so it is at most 20 iterations per second.

Also would be glad if be warned of any other heavy places in isxeq2/ogre API.
