I don't know if this issue has been discussed before, but i discovered this week, that the lftp default debian-testing package, compiled with gnutls, without ssl, uses up to 80% cpu when downloading from an ssl/tls enabled ftp site (data encryption enabled). Now i compared it to a self-compiled lftp version, 3.5.6 --without-gnutls --with-openssl, and this version only takes about 5% cpu when doing the same transfers from the same site. And yes, encryption is on, the site enforces data-encryption for all transfers.
Any ideas? Thorsten
