Moving about the blocks in a simple GRC flowgraph is very sluggish when my processor is set to 'Performance' or 'Ondemand'.
When set to 'Powersave', moving about a block in exactly the same flowgraph works super fast again! The CPU frequency changer I'm using on my installation of Ubuntu 14.04 LTS x64 is called 'indicator-cpufreq' and if installed and run you will be able to access these different processor speed options: sudo apt-get install indicator-cpufreq The speed is confirmed with 'cat /proc/cpuinfo | grep "cpu MHz"' to be 800MHz on 'Powersave' and 2201MHz on 'Performance'. It would be interesting to know if you are seeing the same behaviour.
