Is there a way to reduce delay between database reading/writing?

@Kevin.Collins @pturmel Thanks for the reply.
I changed some configurations and the delay is now reduced to about 3sec, but I want to improve it even more. Is there anything I can change in order to get the delay closer to 0sec or 1sec now? Answering questions 1, 2 and 3: I’m using ignition and the database in the server computer, so there is no way the clock is unsynchronized and that’s my config now:

I don’t know now how to answer questions 4 and 5, but I’ll try to as soon as possible. Thanks!
