Re: innodb_read_io_threads and innodb_buffer_pool_instances
I don't know the answer, but I would guess that you would have 10 threads. Here's why...
"Threads" exist to get some parallelism for I/O. -- We are talking about milliseconds.
"Instances" exist to avoid some delays in getting mutexes (locks) -- We are talking about nanoseconds or microseconds.
That is, the mutex time is so much faster that it is relatively insignificant compared to how long one thread sits there handling one disk block.
