Using a parallel foreach loop to run multiple threads
A while ago, during a work retreat (yes, the company I work for is really that cool), Graham Rook, who is one of my colleagues, showed me a parallel
foreach loop. It certainly speeds up processing a great deal. But here's the rub. It makes no sense using a parallel
foreach loop if you're dealing with small amounts of data or little tasks. The parallel
foreach loop excels when there is bulk processing to do or huge amounts of data to process.
We will start off by looking at where the parallel
foreach loop does not perform better than the standard
foreach loop. For this, we will create a small list of 500 items and just iterate over the list, writing the items to the console window. ...
