The source code is available and the best source to answer a question
like this.. See wpa_supplicant_ctrl_iface_select_network() in
ctrl_iface.c.

If you are using ap_scan=1, quite a bit of time is used to run through a
scan of all supported channels. 300 ms is actually quite fast for this
and I would assume you are using 2.4 GHz only card which limits the
number of scanned channels.
