Add a perf test for the refresh_index() function to compliment the existing read()/discard() in a loop perf test added in 1ecb5ff141f (read-cache: add simple performance test, 2013-06-09). Since this test is much slower (around 10x) than the previous read()/discard() test let's run it 100 times instead of the 1000 time the first one runs.
