Do you mean that you re-powered the card and re-established the session 
for each signature?

That would slow down the procedure by a factor of (more or less) 3, am I 
correct?

What I do is just connect, login (C_Login) than start signing (OpenSSL 
signs using the RSA op provided by engine_pkcs11 that wraps the PKCS11 
module)...
