I made an assumption there: by 100% CPU you meant running a small number
of additional CPU intensive process that pushed CPU utilization to 100%.
If that is what you did then that is not enough.

A real server can have hundred of threads all using CPU. A few of these
would push CPU utilization to 100% but there are many more. Thus when
the OS schedules any one thread it only gets a few % of the CPU and so
it runs tens or hundreds of times slower than for a lightly loaded
server.
