Maximum pps for small packets size #33

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
It's more question about performance, than an issue.

What factor is limiting performance? I can't get more than 1000pps for 73bytes 
packets.

What steps will reproduce the problem?
======================================
1. Steam control -> Rate -> Packets/Sec
2. Set rate 2000 pps
3. Start generation, check fps sent in statistics window.

What is the expected output? What do you see instead?
=====================================================
I am sending DNS requests with rate of 2000pps. Packet size is 73 bytes. I 
can't get more than ~1000 pps even with 3Gig CPU and 2Gig of RAM PC.

What version and revision of the product are you using (available in the
About dialog)? On what operating system?
=========================================================================
Version 4.3.3, Windows XP, SP3

Please provide any additional information below.
================================================
B.t.w, seems Frame Received Rate is not shown correctly - it's two times bigger 
than real rate seen in Wireshark for the same time period.

@andrej

2000pps shouldn't be an issue at all. What happens if you configure the rate as 
4000pps instead of 2000pps - do you still see rate of 1000ps or more?

Try sending bursts instead of packets with burst rate at 1 burst per second and 
burst size as 2000 or 4000. 

Save the stream you are using and attach it to this defect.
