Hi alt, something not stable about sending speed.
on some test i make 200/sec, and on some it's 12/sec...
my network is 150/150.
how do you decide in which speed to release it?
can i take any log and send it to you?

i did the test of the 200/sec in the build that was release on : 2.7.0-beta-190910
now i test it with : 2.7.0-beta-190911 and get 50/sec

can framewok version influence it?

Timer in windows is inaccurate the deviation can be up to 15 ms for every tick.
In your case it should be 1000/200=5ms . It is almost impossible on desktop pc.

How do you calculate the speed?

Please try to output new metric client.Metrics.Sent.Requests.PerSecond.
It is the average speed from begin of connection. You can also reset the metrics
client.Metrics.Sent.Requests.Reset();
then it will calculate from point you want.

Have you mean that if you use the version 2.7.0-beta-190910
then submitting works correct in your application?

Network errors can also slow down submitting speed.

Please test only with version 2.7.0. In version 2.6 speed limit was implemented wrong.

Hi alt,
the 120 max speed you saw in the graph was with 2.6 version
the 200 speed you see it's with version 2.7 (on my pc with law bandwidth).
when I upload the 2.7 to the server the speed limit drops to less then 50/sec
where I have a 150/150 line

Please check if Stopwatch.IsHighResolution is True on the server.

Code: Select all

if (Stopwatch.IsHighResolution)
    {
        Console.WriteLine("Operations timed using the system's high-resolution performance counter.");
    }
    else 
    {
        Console.WriteLine("Operations timed using the DateTime class.");
    }
