Random lags/slowdowns

Scenario: Running a big process from the Orchestrator, looking at logs in the SQL Database and seeing some actions, simply like Set Transaction Status take sometimes 0.1 sec and after a few cases processed it takes 2-3 seconds. Doesnt happen only for that particular Action. It could happen for any different action we’ve got and its not delays, waits or anything. Just sometimes some actions take more than they should.

Any idea what might cause that? I did not find any similar topics regarding robot performance that would mention these kind of slowdowns.

Steps to reproduce:

Current Behavior: Random slowdown for a Ui Activities, Components, sometimes taking 0,1 seconds and sometimes taking 2. Inputs and variables are the same for each activity, its just like Robot is lagging.

Expected Behavior: All activities take same amount of time.

Studio/Robot/Orchestrator Version: Orchestrator 2018.1.4 / Robot 2018.1.4 / Studio 2018.1.4

Last stable behavior: n/a
