How to limit the amount of concurrent async I/O operations?

Question

// let\'s say there is a list of 1000+ URLs
string[] urls = { \"http://google.com\", \"http://yahoo.com\", ... };

// now let\'s send HTTP requests to each of these          


        

Answer 1

Although 1000 tasks might be queued very quickly, the Parallel Tasks library can only handle concurrent tasks equal to the amount of CPU cores in the machine. That means that if you have a four-core machine, only 4 tasks will be executing at a given time (unless you lower the MaxDegreeOfParallelism).
