#14 Attachment Encrypt Performance

[Anonymous]

I already make change from String.concat() to
StringBuffer.append(), but the performance have no
effect.

I try to encrypt (3DES, 192 bit) the mail with 1MB
attachment. It's spends 20 seconds And spends another
20 seconds to send the mail to SMTP host.

Any idea to enchance JSMIME and better the
performace? Thx alot!!!
