In both cases above, 50 requests were completed. In the case of 
concurrency=25, however, the 50 requests were completed faster (i.e., 3.46 
seconds vs. 5.79 seconds in the serial case). So, with concurrent requests, 
the time per request dropped from 115ms to 69ms. Did you expect it to drop 
all the way down to 4.6ms (i.e., 115/25)?
