c# - Timing delays using Schedule for NServiceBus -


While using the schedule method for NServiceBus, I see that there is a continuous delay between passed jobs. If my interval is up to a minute, instead of looking at the next job, just one minute away, an additional 5 seconds delay seems to be.

If I set my intervals down in just one second, the additional delay is also 0.7 seconds. The delay in running for more than a minute lasts for about 5 seconds.

There is a code snippet using the minute interval:

  previousTime = DateTime.Now.TimeOfDay; Schedule. Every (Timespane. FormsCunds (60)) Action ((=) = {DateTime timeout = datetime.Now; Servicebus.WitToAlAug (string format ("Start of schedule: {0}, {1} delay" current time, Current time, timeoff - previous time); previous time = date time.Now timeoffs;});   

There is a snippet from my logs:

I have raised a problem in jihab to fix this, see P> If you have an interval < = 1sec, you will not have 5sec delay because we bypass voting and execute that code.
So 0.7sec delay executes the code directly.
