The most efficient way to delete old files with bash

Question

I execute this command every 30 minutes through a bash script (on Centos 6) to delete files that are about 1 hour old. The problem is that the team finduses 45% of my cpu at all times. Is there any way to optimize it. At any given time in the cache there will be about 200 thousand elements.

find /dev/shm/cache -type f -mmin +59 -exec rm -f {} \;
