Hi Dave,
Indeed long time no speak, to much work to little time as usual, I cannot say I found a reference about connection pooling in COM+ but I can tell you it is very much empirically so. We noticed the SVRCONN take a while to close and do not correlate with the number of application instances we have up and running! When the MTS support pack was available I do think I read something along those lines but I am not sure, when I will have some time I will check it out, meanwhile here we assume it is so, because we issue connects and disconnects as much as we need and it does not hinder performance. Hopefully I was clear, if not feel free to give me a call, Cheers Didi ----- Original Message ----- From: "David C.
