Re: .NET slows, COM+ still fast

Thanks for the info.

Do you happen to know if you can scale up or out to help with Web service
performance? It's not ideal, but I think our bigger customers that require
the 300+ concurrent connections would be willing to add hardware if it made
the system work.

I'd hate to write stuff from scratch in something that's not going to be
supported in the near future but I don't want to choose the newer stuff that
doesn't perform.... I'm sure there are many out there familiar with that
pain.

Thanks again,
Mike
