I know it loads programs to the RAM so they can open faster and actually It doesn't really bother me but I just want to ask - Does it really improve performance that much? My system runs pretty fast, considering its age, and I'm just wondering, will there be a significant decrease in speed if I disable it? Again, it doesn't bother me at all, just curious.
The easiest way to find out if you can live with it disabled is to disable it and test the results for yourself.
However, I know for a fact that, although it may speed up app launching, it runs for a considerable amount of time in the background; thereby, utilizing resources that may/or may not slow down your PC while it is running.
In any event, I have an SSD so it is a no-brainer for me. I just disable it. No harm in testing this yourself.
Hope this helps.

Superfetch works even when it is disabled (sort of), it just does not create prefetch files & resets upon restart.
OK, now I understand what you meant. Yes, I agree that once you load a program it will start faster if you launch the program again before restarting. However, you did bring up another thing that could be disabled (especially if you have an SSD):

For the record, I did not bother disabling the prefetcher function.
Yes, I use CCleaner and other cleaners, which clean prefetch files. I have it disabled since install and the difference is obvious, mostly with a cold and warm start of a browser, like 5 secs vs half a second afterwards.
OK, thanks for that information. Here is a cool (portable) utility that lets you examine the contents of your prefetch folder and it even allows you to see the creation dates:
