How many DCOM connections can I have on a Windows NT Workstation? (Does it have a limit of 10, like in shares?) How is performance affected when 20 users connect?
I am not aware of any direct limitations on the number of DCOM connections, but there are a number of environmental considerations. The primary one is whether the ActiveX exe is single-use or multiuse. If it is single use, each instance will require a minimum of 500k of memory on the workstation. If it is multiuse, then the memory requirments are much less, but you have to handle the theading, concurrency, blocking, and other issues. One of the nice things about using MTS is that all the components run as DLLs under the MTS proxy, which is kinda like having your cake and eating it too.
