All tests will be successfull 50% of the time, the other 50% will not be successfull, since theMaps is pre-initialized for each test with keys/values 0-500, and the tests are runned withkeys/values 0-1000.The keys are Strings, while the values are integers.
This page presents the results of executing a performance test of FKache versus java.util.HashMap. The tests was performed on Sep 20, 2004 11:21:13 PM. The tests was runned on Java(TM) 2 Runtime Environment, Standard Edition version 1.4.2_05-b04 by Sun Microsystems Inc.. The operating system was Windows XP. The amount of available memory to the VM was 63Mb.
