I'm not sure. I'm still looking into what can be done to speed 
rsyncrypto up. At the moment, this is consistent with the numbers I get.

As far as I can tell, it's the gzip, rather than the encryption, that 
slows everything down. You can try passing compression levels to gzip 
using the "--gzip" rsyncrypto option.

Rsyncrypto has two keys. One is the assymetric key (which you generated 
as mykey.crt, well done), and another is the per file symmetric key used 
for hot decryption. These are generated in the "keysdir" directory (in 
the case of recursive encryption).

Can it be that you are using an encrypted private key? At the moment, 
rsyncrypto does not support that.

Both my name and my surname have meaning in Hebrew. See 
http://shemesh.biz/sun.html. Surprisingly enough, my surname's meaning 
in Hebrew and in Maltese is the same. Do you know of any connection 
between the languages?
