Good estimates for the speed of many algorithms can be found at 
http://www.eskimo.com/~weidai/benchmarks.html , while the system is a bit 
old, the numbers are still relatively valid, considering that you will have 
other overheads involved. Just to save you a trip 3DES comes in around 
10MByte/second, and AES up to 6 times that speed.
