Library 4.8 speed verses all after that

Need Help With My Project
1

I keep waiting for this to be fixed and it appears that it is not going to be.
Ever since Library 4.8 the counter in my application falls behind. It’s on a 1-second interval.
Just tried the new Library 5.3 and still the same.
I have created a video of my app that has been compiled with Libabry 4.8 first and you will notice that the
auger status widget clicks right along at 1-second intervals just fine.
2 nd part of the video was compiled with the latest Libary 5.3 and you will notice the auger status falls behind as much as 5 seconds.
Whatever was changed in Library 4.10 and above all have this problem.
It will even show up on the simplest app with a single widget displaying a clock at 1 second interval.
I know some work was done in the library to try and prevent flooding. I think this a what is causing this delay.

Here is the video.

I see a blank spot :wink:

In what way? 0.1 second, 2 second, 5 second delay?

Possibly… but also doubtful. I have many strange projects… some that push the limits on timing, but they still keep the correct timing… although my one ESP32 project does get a bit strange at “times”… but that is more an ESP32 thing, not Blynk.

The solution will most likely be to tailor your (mystery) code for better efficiency so that the anti-flooding doesn’t need to affect timing.

If you want your issue to be addressed, please provide the simplest example that clearly displays the problem, and steps to reproduce. Thanks.

Actually library 5.3 is better than 5.2 in this case. So it appears to be getting better.
Create a new project with 1 value display widget. Assign V10 as input.
add a real time clock to it. That is all that is needed on this test.
Create a new sketch in Arduino and paste the following code.

Compile using Blynk Library 4.8.
Run the app and watch the seconds tick . occationally you will see a 1 or 2 second lag time. Not very often with 4.8.

When ready recompile useing 5.3 and run app. You will see more frequent lag times occationally up to 3 seconds.

It is really pronounced when you are running a large program with more timers.
