Yes I understand that this test is not relevant!
The one think I didn't understand is why two different services working
with 2 different users share 1 core at 100% and not working on separate
cores/treads ?
Even if the requests are not overlapping i think the two services should
work independently to each other or I'm mistaken somewhere?

PDNS process all the requests sequentially not paralel?
If that is not a relevant test let me know how to.
We were talking about performance of notify etc. And now you're
posting something about general query performance.
I think your question about using a single core for master/slave
operations was answered. If you have more questions about that subject
say so.
If you want to talk about general performance (measurement) start a new
subject.

For example if the mariadb get 70% pdns 30% if i check the load by cores
one core has 0%id all other 3 are near 100%id .
here are some screenshots
Looks like sequential operation to me:
1. pdns sends a query to mariadb (goes to sleep waiting for response)
2. mariadb processes the query and sends back the response
3. pdns processes the response, then sends the next query to mariadb
etc.
Without overlapping requests, pdns and mariadb will never be working at
the
same time.

Additionally, the master/slave work is done in a single thread. That
is generally good, since the other threads should be busy serving
requests. If you have a setup where there are little requests need to
be served, oh well, making the master/save operations multi-threaded
is probably not worth the added complexity.
