The above search is looking for setuid binaries, if you mount /exports
as noexec and/or nosuid then it wont get searched. 

You may also need to curtail the locate search as someone already
mentioned, although that's only weekly and it only searches
directories that the user "nobody" can read. 

7 hours does seem a very long time though, these searches only take a
few minutes for 1.3TB on my desktop machine, and it's several years old.
