Thank you for having included this ABI description. This is very helpful. Please follow the format documented in Documentation/ABI/README and make sure that all text, including the description, start in column 17 and please use tabs for indentation.

Is it explained somewhere how the optimal number of connections is determined and also according to which metric the number of connections is optimized? Is the number of connections chosen to minimize latency, maximize IOPS or perhaps to optimize yet another metric?
Thanks, Bart.
