    Everyone agrees that cross-context calls are more expensive than
    same-context calls because of the interception. The position I took in my
    book was that you should only pay that price when you need to. I did not
    address the issue of COM+ interception overhead relative to MTS, nor have I
    tested it. The topic has come up on this list before and I have
    *hypothesized* that increased overhead in interception might be responsible
    for the performance decline Charles and others have seen moving from MTS to
    COM+. I suggested reducing contexts as a possible solution to the problem
    Charles is having. I certainly do not claim that that is the only possible
    explanation and since I never saw the source code, there wasn't much I could
    do to verify it.

    Yes. Something is making Charles' real world applicatoin run slower under
    W2K/COM+. So what is it?

    Thanks,
    Tim-
