Hi, I am using stunnel as an encrypted channel between one server and multiple clients. Each client will transfer a very small piece of data every 20 seconds. Therefore I want to compare the tradeoff between maintaining multiple sessions with tearing down and re-establish connection every time. I read the performance table in stunnel doc and got a brief idea, but I hope to evaluate the performance for my specific hardware and software setup to make a better decision. I guess my question is how to measure the Max. concurrent sessions? Should I start multiple stunnel instances on client side? Also, how can I tear down a connection automatically after each time data transfer? Thanks Yuqiong
