Hi, First of all, there is a typo error in this example. The main HTML page is a copy/paste of the first example ("Worker example: One-core computation").
My point here is to ask for a new attribute for the navigator object that could describe the "best" number of workers in a delegation use case. In the delegation example, the number of workers chosen is an arbitrary 10. But, in a single-core processor, having only one worker will result in more or less the same running time, because at the end, each worker runs on the only core. This is just a waist of memory (and maybe time because of scheduling cost). On the other hand, on a 16-core processor (which doesn't exist yet, but is a realistic idea for the next couple of decades), the task could be executed faster with 16 workers. I've given the examples with cores, but the problem may be a little trickier. In the case of weird operating system, we can imagine that some ressources (some cores) are not available for user-land processes, so, the number I'm trying to describe is not just a hardware description. We can imagine this ressource restriction in virtualized operating systems too. The current best way to determine the number of worker that yields the ressouces in the best way is to run a benchmark on an increasing number of worker and stop it when the performance improvement stops. I hope you will admit that this way in not acceptable. Moreover, for a totally other purpose, this attribute could be used to make statistics on the spread of multicore processors like the statistics that are already done for operating system or screen resolution use.
