A tad bit high mean response times, I think.
How does that compare with these real-life results?
To wit:

[ Note: The byte hit ratios are a bit off now, at peak usage, they're
        about 30%-35%.
        I know median-service-time is not the same as mean-service-time,
        but the minimum service time for a hit, is around 0.053s,
        comparing this with the dcomm-1 results, I see Cobalt specify
        a mere 1.98s; what did your test come up with?
        And why is it so much higher?
