After configured server signing, file transfer speed is very slow

[Steve French]

In my testing signing is slower than encryption (but only when using
SMB3.1.1 GCM e.g. to Windows or Andreas's Samba GCM branch). With
Andreas's GCM SMB3.1.1 in Samba, I find there to be no need for
signing as encryption is faster.
