How to speed up a slow redirect (using WP)?

Question

WordPress

I set a redirect in htaccess
RedirectMatch 301 ([0-9][0-9][0-9][0-9][0-9]) selftrips.ru/?p=$1
which translates, say,
selftrips.ru/2015 /07/27/21219
in
selftrips.ru/?p=21219
it happens very fast in 100ms ( https://tools.pingdom.com/#!/L0L1u/http://selftrip...
then WP itself makes a redirect to the URL set for this page according to the rules "permalinks"
selftrips.ru/strany-i-mesta/aziya/turciya/sivas-ka...
so this redirect is done in 2 seconds, i.e. 20 times slower
1 Why is it so
2. Do I need to deal with it
3. If so, how
?
from the "canonical" form of the URL selftrips.ru/?p=21219 to the given one?
As I understand it, it is processed 20 times faster

Answer 1

It is executed automatically by means of WP. Another thing is that I myself "provoke" creating an intermediate selftrips.ru/?p=21219 , because I can't figure out how to automatically create a 301 redirect
