Under "normal" web server loads/concurrency that is normal.

Stackless, and asynchronous methods in general, are especially suited
for high concurrency on several orders of magnitude larger than what
threaded approach can handle. Stackless also helps if pre-emption is
Of course, it's always about using tools that fit the problem and
stackless solves some common problems very nicely, but it's not the
answer for everything.
