Problem: about 10 second delay before connection in reverse connection + Plugin

[Sainsuper]

Hello,
i have made many many test, before write this topic.
scenario:
vncviewer started in listen mode with /password parameter

server
using dsmplugin and connect via command line: winvnc -connect -ipaddress:port -run in reverse mode

viewer stay about 10 sec in connection status on "password requested" before connection estabilished.

if start winvnc and manually add new client insert address, connection is fast

if i disable dsmplugin there isn't any delay, connection estabilished fast in commnad line and with add new client
