HOW TO INCREASE THE PERFORMANCE OF YOUR HTC ONE V

CPU

The HTC ONE V houses a MSM8255 processor designed to operate at 1.4GHz .So overclocking it below that range should be fine but never underclock it below 245MHz. If the battery temperature exceeds 114.3 degrees Fahrenheit (45.7 degrees Celsius) then you will need to revert to a lower clock rate, but that shouldn't happen. 

I/O Scheduler/Governor
Best settings is Deadline in combination with SmartAssv2/LionHeart.

General

Its recommended animations in developer settings are turned off or turned down to 0.5x speed
Turning off vibrate sounds/feedback will help with processor load in heavy situations (minor differences)
Setting the launcher to 3 screens instead of 5 
Crossbreeder Mod contains a large amount of tweaks, if you use this mod you will see major performance improvements, Kernel Same Page Merging may be turned on with this device in settings, dont worry about extra CPU cycles or battery life drop, crossbreeder does it all. Just reboot into recovery and flash the .zip file on top of your existing ROM
Enable KSM (Kernel same page merging) for better gaming experience and RAM utilization, compliments well with crossbreeder.
