does narrow improve the performance (font-lock, x-symbol)

Hallo As I complained various times, x-symbol has a problem with large files. I am not entirely sure, whether it has to do with the use of lazy-shot or lazy-lock or ... Or with the way x-symbol has implemented the x-symbol-write-file-hook. Anyhow x-symbols sometimes freezes the whole xemacs and the result is a not correctly encoded file, and in the case of Mule, a badly damaged one. Now I thought that it might help if in the case of a huge file, I narrow to a certain region and do the edit there. Of course x-symbol still has to save the whole buffer but may be fortification is more efficient if the buffer is narrowed? Can anybody comment on this?
