It's a valid concern, but fuse does not "execute a script" for every operation. The script is always running, sort of like a server for the pseudo-filesystem. Each requests causes a few lines in the script to be executed. There is no process creation and dispatch for each operation, only a process wakeup for each operation. It is impressively lightweight and it's worth trying before dismissing it as a resource drain. But anyway, here's another idea for you-- Export a new directory that contains links to only those the files you want to export.
