No it wouldn't. The reason for psp install data is to stop the umd from needing to be read so you kinda get everything fastest since you psp doesn't have to read the umd since some of the data is just right there for it to read. Since jpcsp doesn't need to read a disk and all the data is already there(just in iso format) there's no need for data install because its running as fast as it would be with it anyway. It would only speed up loading times and as far as I can tell there are any loading screen slow downs unless its decoding audio.
