I need to clarify a bit of what I wrote. In the '-c 100' test AOLserver does of course not serve more requests per second than the 6.something. What the numbers show is that it will, on the avarage, not slow down or crash even if hit by a load surge above what it can cope with from a pure requests-per-second point of view. Two thirds of 100*60 requests cannot be answered per minute, of course.
If you need to serve 100 pages per second sustained over longer periods of time, then you will still need to either use an external proxy, implement caching in RAM within AOLserver or add more AOLserver instances.
