| Need some advice. I have 5 clients using the tcpip client connection method, all using the same channel. Do you guys think it would be better if i created a seperate channel for each client, also the one channel is SSL enabled. So I would have to make each channel SSL enabled. Any insight into this would be fantastic. |

Actually the clients will be using the same channel definition. They will be using separate channels - ie. separate TCP/IP connections. Check output from
while your clients are running. |

mvic correctly points out the difference between a "channel definition" and a "channel instance" (which gets it runtime attributes from the definition).
I've seen two reasons for using multiple definitions:
(1) You need to have different characteristics on the channel (enabling SSL, exits, mcauser, ...) and
(2) You be able to easily monitor the "type" of connections coming in (ie, you might want to name and use channels based on stuff like: application area, geography, type of user ... etc).
others might add more reasons ....
from a performance perspective, it doesn't make any difference if you have 1 definition used to create "m" instances or "m" defintions to create "1" instance each.

When one of them starts looping and creating hundreds of instances, you can force stop that channel and the others are uneffected.
