Machine:
AMD Athlon 1100Mhz
1GB PC133 RAM
Windows 2003 Advanced
On-board NIC (SiS 900)

Note: Pretty crappy NIC, I know, but the goal is just to see the speed difference between SSL and no SSL transfers, not measure the transfer speed.

Note 2: Added 40 bits encryption, which shows in FlashFXP as RC4 128 bits.

Results:

During SSL Transfers, CPU was maxed out by FlashFXP and ioFTPD:

Conclusion: SSL transfers using 128 bits encryption go about 53% of the speed of no SSL transfers.
