Avoiding context switches is not a problem async solves. A threadpool popping work items from a queue(or something like lmax disruptors) has the same effect on context switches. The only thing one could argue is that the async runtime's threadpool "homogenizes" work. Again, yet to encounter a case with web services where this was the issue.

I'm not familiar with FPGA scheduling, are there any resources that explore the issue? I was under the impression it's akin to GPU compute where the main bottleneck is the bus.
