Java release to release comparisons

All the other tests of the JSSE study used Java™ Version 5.0 SR 9. The tests were repeated with two other Java versions, in order to assess the impact on the results.

To identify differences with the Java releases before and after the release used in this study (Java Version 5.0 SR 9), the tests were repeated with all the possible combinations of packet sizes and ciphers using:
  • Java Version 5.0 SR 7
  • Java Version 6.0 SR 4

The only difference was that Java Version 6.0 SR 4 did not support the hardware encryption, so in this case only software encryption was tested.

No significant difference was observed between the two Java versions studied, with respect to either throughput or CPU utilization. The JSSE APIs in the Java software performed equivalently in all tests.
