BIG BAD Throughput issue!

PeterUK

USG FLEX 200H V1.39(ABWV.0)

I had a bad bad feeling when I went to test this...and my feeling was sadly right! And on top of that I think I know whats in ZLD was added to uOS to cause this and I hope I'm wrong!

So here is the simple test local HTTP server download a file by Edge over a two 2.5Gb ports in a bridge.
Let me start with showing the V1.39 Throughput you might think 1.2Gb is pretty good for a bridge

and 1.9Gb for SNAT ok

and now V1.38(ABWV.0)ITS-26WK16-m11228 for just the bridge thats a jump!

So what do I think is unfortunately causing this? Forward path out a given interface to reverse path in to another interface. In short before V1.38 there was a setup I did for ZLD that could not be done by uOS then V1.39 happens and I found I could and I hope I'm wrong as to the added support caused this.

Hi Peter,
so also my speedtest problem is valid.
Do you think it's the same issue? I could also revert the configuration to 1.38, but unfortunately I'm not at home today.
What could be causing this problem? It's interesting, because if I can still get 2.5GB with the bridge, it would have solved a lot of problems with different subnets.

I also tried to disable all the IPS/Security for not overload the CPU but the problem still present.

I've notice that when I try the speedtest, the CPU Load raise up to 50/55%, causing full load (exactly 100%) on CPU3 & CPU4 (I think are the fast-path CPUs), instead CPU1 & CPU2 are irrilevant (5/10%), for both download and upload tests.
