public class TestSpeed

extends Object

This class measures the execution speed of the IAIK-JCE cryptographic implementations for typical applications. This class can also be used to benchmark other JCE 1.2 compatible providers, like the default Sun provider for MD5 and SHA-1 hashes or the SunJCE provider from JCE 1.2. You should notice that the IAIK provider is significantly faster on most algorithms.

Note: This class has been adapted to work both with and without a preemptive thread scheduler. The functionality and results are the same, however, when run on a non preemptive scheduler the setup time for each test will be approximately 0.5 seconds longer. Again, this has marginal effects on the test results at most.

Note: When using HotSpot or similar virtual machines the test results may not be completely accurate, in particular the result for the smallest block size may be too low; also the scheduler type detection may be incorrect. This will not happen on ordinary JIT compilers.

The test goes over several block sizes:

md2, md5, sha, sha1, arcfour, des cbc, des ede3 cbc, idea cbc, rc2 cbc, blowfish cbc for 8, 64, 256, 1024 and 8192 bytes; rsa for 512, 1024 and 2048 bits.

The results are printed in 1000s of bytes per second processed.

Usage: java demo.TestSpeed [p=name.of.provider.class] [t=time] [hashes|ciphers|rsa|all]

• Use p= to specify the provider to test. Default is IAIK JCE (iaik.security.provider.IAIK) but you can also benchmark sun.security.provider.Sun, com.sun.crypto.provider.SunJCE or any other 1.2 compatible provider.
• Use t= to specify for how long each speed test is done in seconds. Default is 3.0 seconds, you can also specify e.g. "1.5"
• Select which tests are to be conducted: "hashes" will do MD2, MD5, SHA-1 only, "ciphers" will do only the ciphers, and "rsa" only the RSA algorithm. "all" will do all of them, it is the default. Any algorithm not implemented by a particular provider will just be skipped.

The results below where obtained on an AMD K6-2 333 Mhz, 128 MB SDRAM running Windows NT 4.0 SP4 Workstation network connected with standard services active. The tests were done on IAIK JCE 2.5 release with JDK 1.1.8 and Symantec JIT, each test for 4.0 seconds.
