Hi Pau,

I needed to set the cpu governor to performance during the test execution to get the best of the device, but I don't want the device to be always in performance mode, as it is a waste of resources. 
I did it in the srs-ue as it's the class that has all the knowledge about what has to be done and in what order.
For adding this feature in the script that launches osmo-gsm-tester, it will need to parse the information of the test to retrieve the resources and decide which one should change the governor, but it is already done by osmo-gsm-tester.
As I said before, for the second option, I don't want the device to be always in performance mode, just only the test, so the device can be cooler and with less consumption.
Do you have any other suggestion when I can place this funcionality.

Thank you very much for your comments, they're giving me a wider vision of how osmo-gsm-tester works
