| Network Communication | Encryption Latency | Network Latency | Overhead |
| (TD msecs) | (TE msecs) | % | |
| Intranet | 0.44 | 2.7 | 16 |
| Internet | 0.44 | 62 | 0.7 |
| Serial Port | 5.14 | 15 | 34 |
From the above table we find that, for communication over the internet, encryption latency is a very negligible fraction of the network latency. However, on a local intranet, where the network latencies are low, adding encryption could be a significant overhead. Considering the devices to be as powerful as a PentiumPro or a Pentium III, this overhead could be anywhere between 10% and 16%. This is the maximum overhead due to encryption, as we ignored all other latencies that could be introduced by the applications themselves. For small devices like a PalmPilot, this overhead could be large, up to 34%.
