Hi,
I was quite enthusiastic when I heard that lftp supports gnutls now.

However:
With gnutls: Transfer speed with ssl max 1.1MB/s, 100% CPU usage
With openssl: Transfer speed with ssl max 7.0MB/s, 60% CPU usage

Is gnutls generally slow, or is it related to the gnutls implementation
in lftp?

Well, it's quite important to understand that openssl is really heavily 
optimized, which I haven't seen so much in gnutls. These performances 
doesn't surprise me much.
