This object-oriented variant of the Richards benchmark provides for a more straightforward comparison between OO languages.

Tcb and Packet objects provide accessor methods, procedures or properties, but no direct access to private instance variables. Each task is represented by an object, with local registers V1 and V2, and a single method which implements the task function.

Look at Richards Bench for a different style of implementation.

Measurement

Timing begins after parsing the command-line and ends before exit - see the source code. For each start value (10,000 to 1,000,000), the test is repeated, until the mean of 5 timings is within a 95% confidence interval.
