one of my customers complains about missing/big delay of DLR
when i use client.DeliverAsync, without await first,
is it possible that there is some queue that wait for release ?
how can i check it?

Do you use .Result or .Wait for the Task?

No,
this is why i asked if there is possible a queue of the DLR? and how to check it
is there something under the Metrics for this?

Could you explain in details? When you send a DLR? What does continuation task after DeliverAsync?

It can be any reason. The customer can block reading from network and you get SMPPCLIENT_RCVTIMEOUT status for DLR.
You can use client
metrics to check it.

Hi Alt,
i tried to do a load test,
sent to 10200 phones with 300 chars.
the DLR in my db toke : 262 seconds
the DLR to my log toke : 528 seconds,
this is after i sent them in groups (more the one time in a DeliverAsync command).
all is done on my pc.
any way to improve it?
is it a reasonable time?
