Rooted M9, S-Off.... Using EX Kernel manager and having used the ElementalX aroma installer etc I have chosen my i/o scheduler to be FIOPS. I am running newest Viper ROM 4.3.0 (it lets me pick read ahead size, I/O scheduler etc in their Venom tweaks section), I also have ROM toolbox Pro ( I was using the CPU profiles option) and No Frills CPU Control installed (lets me pick min/max clock frequencies, governor, I/O scheduler) .They all seem to give me access to I/O changes. I want FIOPS but throughout the day when I check my phone it reverts to SIO... Madness! Do I need to lose one of the above mentioned apps? To be clear, I am choosing what I want with a combination of the kernel's aroma installer and the kernel manager app but my choices change on me more often than not. I have NEVER made a conscious choice of SIO with any of these apps etc. Do I have too many cooks in the kitchen with these apps?
