Thats out of node's scope. If you've got too much work to do, and too few cores, well, shit get scheduled. Plus, there are a lot of processes already fighting for some CPU juice.
Essentially what you're talking here is CPU scheduling. danmilon. On 10/26/2012 02:49 AM, Jimb Esser wrote: > That is exactly what node seems to do with the zlib API.
