Hi guys,  
Just a quick question: does the function `system.alarm.getRosters()` gets the information directly from the gateway?

Best regards, Guilherme

So, could this function create some gateway slowdown and/or high cpu/ram consumption if every client runs it 3 times every 5 seconds (in runscript expression function)? Obviously it depends on the Ignition’s machine specs, but I just want get a rough idea.  
I’m just asking because the RAM and CPU consumption were running pretty high until I removed this function from the project. Also due to an unrelated problem we had to restart the server, and now the both CPU and RAM are pretty smooth, and now I can’t tell if it was due to this fix or the restart.

Yes, it could cause CPU problems depending on the number of clients.

You have to be careful with the `runScript` expression because it’s easy to abuse it like this and cause problems.

Thanks! Yes I agree, I’m always trying to hunt them down from more older versions of the project (I think this was the last one).

Also, this is kind off unrelated (should I make a bug report about this?): When I changed the Client Maximum Memory to 2048M some users were unable to start the project because their Win10 was pointing to the 32-bit java version. I bet this kind off stuff will disappear with Ignition 8.
