earlier i thought that tls cannot use async tcp, but it actually turns out that if tls is enabled, tcp async capability has to be turned off and is thus lost: Note: Using TLS over asynch TCP is not supported at the moment. If you use TLS you have to disable asynch TCP! if it is not possible to make tls use non-async tcp at the same time when async tcp is enabled for non-tls tcp transport, then my opinion is that we should wait that tls can use async tcp before sr is released. -- juha
