The program computes values of 4 Bessel functions for 10 million different argument values. This evaluates mostly the performance of the float point additions and multiplications. Divisions, sqrt, sin, cos and log are also evaluated during the run.

Compare your results with this table. The speed estimate (the "score", normalized to the 500 MHz P3 computer results) varies between different processor architectures and depends on the used compiler. Execution of Java/javascript in your browser is usually slower than that of native program as should be clear from the above.
