I own a tf700t running android 4.4.4, but I'm not happy with its performance, as there are many lags.

So I thought about locking some of the cpu cores at a high frequency (yes I'm aware of the battery drain!), but I can't figure out a way to do that.

With System settings I can set the frequency, but this is only for the first core, the other cores are shut down regardless (I can check it with the app Quad Core Manager+.) With this app I tried to lock the core, but it wont work as well.

My next approach was through Tasker, but this way I can set the frequency only for cores that are actually awake!

Do you have any ideas?

    Instead of "forcing wakelocks": Have you tried to adjust the CPU governor, e.g. set it to "performance"? The governor is who decides how fast a CPU is pushed-up to max-speed and how long it stays there even if there are no tasks for it. Default often is "on-demand"; "performance" keeps the CPU on high frequencies longer. – Izzy Dec 9 '14 at 17:05
  • I did that, with the effect that the first CPU is set to performance, the other kernels are shut down regardless. But for me this is not smooth enough ;-) – S. Valant Dec 10 '14 at 9:05
  • What did you use to configure the governor? I've got no experience with that, but different apps might have different degrees of "compatibility" with multi-core. I've got a list of apps for CPU settings you might wish to take a look at. // Just found Kernel Tuner explicitly claiming multi-core support: Control each CPU Core of your device independently sounds promising, doesn't it? – Izzy Dec 10 '14 at 9:33
