I had similar results. Starting 4 listening threads and 4 receivers <br>
threads (by adding the same backend 4 times) boosted my performance - <br>
almost linear.<br>
<br>
If it still does not work your should post your config (and first test <br>
without any rules to avoid performance issues because of rules)<br>
<br>
