Please note:

The most time intensive inner loop (about 20 lines of code needs about 80% of the running time) is highly optimized in C to achieve the best performance.
Especially in the Windows version this code is about 25% faster (depends on platform) because it is written in Assembler x86 and optimized for Pentium(R) Pro, Pentium(R) II, and Pentium(R) III processors.
The performance index maybe higher for a higher library version number using the same work unit ID.
The performance index maybe higher by using Sun JRE 1.4.1 compared to Sun JRE 1.3.1.
The performance index can also be about 30% higher if you change the priority of the process to high.
Sometimes there may exist ranges of zeros where the performance index could be very low, e.g. close pair of zeros.
The performance index depends partly on the work unit ID.
The performance index will decrease about 0.3% per day because the complexity to separate the zeros is growing continuously. Therefore, the perfomance index will be 10% lower in about 30 days.
