Slow simple single insert in MariaDB (MySQL) - 50 ms?

Instead of backticks in the values use single quotes.

Finally I had to implement some app-level transaction grouping logic to reach needed performance. As I understand now, this performance is expected for my hardware. Probably, it will be much better on server hardware (no time to test).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
