Very slow loading connections manager with saved many connections WinSCP v 6.1.1.

Hello,
Every time I want to connect to a server, I have to open the connection manager. Unfortunately, the window takes manys seconds to load, which is terribly annoying.
Can you do something about it?
I have hundred connections with passwords saved.

Is this new to 6.1.1 or any recent version? Or was it always that slow?

The last time we optimized loading of sites was in 5.6.2:
Issue 1220 – Optimize startup time
Can you test that version just to see if it got slower since then again?

Version 5.6.2 works very well. Thanks

So can you please try to find out what version did introduce the slow down?
