Only if there are spare resources left to saturate the connection pools, which didn't seem to be the case. If the system as a whole is well saturated, and the python processes dominate the system load with a DB load proportional to the requests served, then I don't think we would hit any external bottlenecks. The benchmarks performed are not that great (e.g., virtualized, same machine for all components, etc.), but I don't think the errors are enough to throw off the result. Note, of course, that such results are not universal, and some loads might perform better async.
