Understanding the factors that affect the performance of PLINQ (speedups)

The primary purpose of PLINQ is to speed up query execution by splitting the task and executing it in parallel. However, there are a lot of factors that can impact the performance of PLINQ. These include synchronization overheads to do with chunking and partitioning, as well as scheduling and collecting results from threads. PLINQ performs best in delightfully parallel scenarios, where threads don't have to share a state and don't have to worry about the order of execution. Being delightfully parallel is ideal but not always achievable due to the nature of work. Let's try to understand the factors that can impact the performance of PLINQ.
