Parallel Enumeration with ForAll

So far, we’ve been using a classic foreach loop in conjunction with a PLINQ-based query. Although this is the most obvious and natural way to consume results of a query, we can do better when we’re facing concurrency. Maybe the results of the query can be consumed in parallel as well, which will allow for a higher throughput. You can see why this is the case in Figure 20.17.
