Ok, so I have enabled the debug. And results are what I expected (if I understand that correctly) - query and processing combined takes fraction of a single second.
Just out of curiosity: you are using 4011 as sampler for documentation - Is that something that you have on your own ? → I do not know what a platform are you using for the HA itself but I am pretty sure that issue lays somewhere on the HA side - some kind of worker configuration or so.
