Actually, it should improve I/O throughput. What it might hurt is computational performance, but only at the expense of benefiting other processes.
The reason it benefits throughput is that file I/O is definitely marked interactive, and that results in file I/O being able to quickly wake up, dispatch the I/O, and go back to sleep. Its the usual treatment given to I/O, and it works.
