Integrated Architecture: Encryption Overhead

• Throughput using 2 servers:

No encryption 71.05 Mbs

Client-Server solution 22.41 Mbs

• Amount of encryption one server can do without doing any other work:

Blowfish 128-bit key 185.6 Mbs

AES 128-bit key 77.56 Mbs

AES 192-bit key 66.98 Mbs

AES 256-bit key 59.38 Mbs

667 MHz dual-processor, OpenSSL 0.9.7

CPU is the bottleneck !
