Most likely because the number crunching is hap
Just to speed things up a little more...

Hi!
I'm using a very simple algorithm to encrypt files sent from the server
"On Demand". The algorithm uses XOR for the encryption. My problem is
that the code is very slow, it can only process about 40 KB per second
on my system, so my question is, is there any more speed optimized way
to write t
