Ive used it a few times and were the speed increase isnt noticable by humans it is a very impresive start and its only going to get better; well worth the small amount of effort required to download and install it if you ask me!

Quote:
2x to 100x speed-ups, typically 4x, with an unmodified Python interpreter and unmodified source code, just a dynamically loadable C extension module.


You can also find some bench marks using Pysco and Zope here:

It didn't speed up launch time of your program right? I didn't see any difference. Should it be used for a program like html editor and things like that?

Any program that in 90 % based on human-interaction will not notice a speed improvement as it will spend most of its time waiting for you.

But - If the program is slow for the user then it indicates a design problem that needs to be fixed by re-working rather than Psyco optimization.
