Re: [abc] Observer slowdown and approve numbers - help

I've taken a profiling run of the pure aspect version, and had about 50%
of the time spent in Thread.sleep() and Object.wait(). Admittedly I ran
the full 100K iterations with the aspect version, but only about 4000
with the TM, as profiling really slows it down.
