Chatraliya, welcome to Android Forums
I moved your thread into the All Things Root section since it's related to rooting the device.
With the Android OS, the number of apps on the device shouldn't impact it's speed as Android is very good at maintaining memory to maximize performance. It might be just one of the apps you have installed causing problems with the OS.
A factory reset doesn't have any impact on the hardware or default status of the software so this doesn't cause any problems.
If you are interested in rooting the device, please see the following guide:
[GUIDE] How to Root the HTC One V
Unfortunately there are presently no custom ROMs that improve performance. And as of now, nobody has produced an overclock kernel. But rooting will allow you to uninstall factory bloat and other unwanted apps, plus backup your ROM and run rooted apps.
I hope this helps!
