Data Parallelism (Task Parallel Library) with MaxDegreeOfParallelism set as ProcessorCount

It could be beneficial to run multiple threads to perform operations on different segments concurrently, so that certain tasks can be completed quicker (like some data updates using some services), and Data Parallelism   could help you, and in this scenario you can benefit from a powerful processor by writing a code as follows; ParallelOptions options = new ParallelOptions() { MaxDegreeOfParallelism = System.Environment.ProcessorCount }; Parallel.ForEach(mdList.AsEnumerable(), options, async row => {    result = await ProcessATask(param); }); For debugging purposes; you can replace the ParallelForEach with this following line to your checks for certain items; Parallel.ForEach(mdList.Select(“numbertocheck”).AsEnumerable(), options, async row => {    result = await ProcessATask(param); });

How to: Cleanup IIS Log Files

If you have got a Windows Web Server, it is possible that IIS is enabled to generate the IIS Log files and over the years this could cause some disk space problems. In order to clear up the disk space; one good option is cleaning up the old IIS log files automatically by using a Windows Scheduler Task and a Powershell script.
