But could be disk intensive. High system loads are usually indicative of the I/O subsystem being much slower than the kernel is trying to push or pull information to/from it. Can't be that disk intensive, its only printing a max of 40 lines of html each time.. and that would all be drawn into memory while perl is compiling it..
