Software Cryptographic Api Performance - IBM 170 Servers Manual

8.3 Software Cryptographic API Performance

This section provides performance information for System i systems using the following cryptographic
services; i5/OS Cryptographic Services API and IBM JCE 1.2.1, an extension of JDK 1.4.2.
Cryptographic performance is an important aspect of capacity planning, particularly for applications using
secure network communications. The information in this section may be used to assist in capacity
planning for this complex environment.
Measurement Results
The cryptographic performance measurements in the following three tables were made using i5/OS
Cryptographic Services API and Java Cryptography Extension.
