.NET Assemblies session.SynchronizeDirectories perfomance...

I have a performance issue with SynchronizeDirectories,
Synchro with winSCP, works very well
but with session. SynchronizeDirectories, I get a very slow transfer speed!

I am in C#, in FTP mode

Thank you for your attention

Lionel

Just for info:

With winSCP:
~100 MB/s

With Library:
~10 MB/s

PS
FTP Server : QNAP 853a
Visual studio 2017 c#
i7 8Gb ram, SSD
