What Kind Of Performance Issues Does Vpn Raise? |
|
Answer» Encryption takes more horsepower than sending data in the clear. It really shows up on mobile PCs transmitting large hunks of data - for example, a POWERPOINT presentation - over a dial-up PHONE line. FIREWALLS and other server systems should employ hardware crypto ENGINES. With these there are no performance issues. I expect that this functionality for mobile PCs will MIGRATE to PC cards with crypto engines. When will this happen? Within the next 18 months.
