Currently we created a thread pool (With 64 max threads per pool) for each virtqueue. We hoped that this will provide us with better scalability and performance. But in practice, we are getting better numbers in most of the cases when we don't create a thread pool at all and a single thread per virtqueue receives the request and processes it. Hence, I am proposing that we switch to no thread pool by default (equivalent of --thread-pool-size=0). This will provide out of box better performance to most of the users. In fact other users have confirmed that not using a thread pool gives them better numbers. So why not use this as default. It can be changed when somebody can fix the issues with thread pool performance.
