All of this technology -and software has evolved since, but the gist of the results remains the same. -<p> -The program sizes include companion libraries. The shrinking step produces the -best results for programs that use only small parts of their libraries. The -obfuscation step can significantly shrink large programs even further, since -the identifiers of their many internal references can be replaced by short -identifiers. -<p> -The Java 6 run-time classes are the most complex example. The classes perform -a lot of introspection, interacting with the native code of the virtual -machine. The 1500+ lines of configuration were largely composed by automated -analysis, complemented by a great deal of trial and error. The configuration -is probably not complete, but the resulting library successfully serves as a -run-time environment for running applications like ProGuard and the ProGuard -GUI. -<p> -For small inputs, timings are governed by the reading and parsing of the jars. -For large inputs, the optimization step becomes more important. For instance, -processing the Java 6 run-time classes without optimization only takes 2 -minutes. -<p> -Memory usage (the amount of physical memory used by ProGuard while processing) -is governed by the basic java virtual machine and by the total size of the -library jars and program jars. - -<hr /> -<address> -Copyright © 2002-2014 -<a target="other" href="http://www.lafortune.eu/">Eric Lafortune</a> @ <a target="top" href="http://www.saikoa.com/">Saikoa</a>. -</address> - -</body> -</html> |
