While this is nice because it may give you nice numbers it's important
to remember that this does nothing have to do with what you'll see in
production. Everything you will see in production, bottlenecks,
throughput, latencies, memory usage, cpu usage will be drastically
different. The numbers you'll get have absolutely no significance.
You'll probably benchmark how fast Seaside can create new sessions
because every request creates a new session.
