 that are being processed by C<IO::AIO::poll_cb> in one call, respectively
 the maximum amount of time (default C<0>, meaning infinity) spent in
 C<IO::AIO::poll_cb> to process requests (more correctly the mininum amount
 of time C<poll_cb> is allowed to use).
+Setting C<max_poll_time> to a non-zero value creates an overhead of one
+syscall per request processed, which is not normally a problem unless your
+callbacks are really really fast or your OS is really really slow (I am
+not mentioning Solaris here). Using C<max_poll_reqs> incurs no overhead.
 Setting these is useful if you want to ensure some level of
 interactiveness when perl is not fast enough to process all requests in
 time.
 For interactive programs, values such as C<0.01> to C<0.1> should be fine.
 Example: Install an Event watcher that automatically calls
-IO::AIO::poll_some with low priority, to ensure that other parts of the
+IO::AIO::poll_cb with low priority, to ensure that other parts of the
 program get the CPU sometimes even under high AIO load.
    # try not to spend much more than 0.1s in poll_cb
    IO::AIO::max_poll_time 0.1;
