Hi Florin, Thanks once again! I was in the middle of collecting a bunch of information to respond (basically nothing interesting in logs and the client does not crash, it just sits there), and then on one miraculous run it actually worked. I was hoping for a bit more performance (I only got 2.89 Gbps) but hey, 3x improvement is a great start ;-)
FYI the server-side VPP instance crashed at the end of the test and I didn't get a chance to collect anything. The rest of the email below is from what I was typing before the test worked (I didn't do anything differently that I am aware of...). Regards, Dom --------------- From failed test runs: -------------- The iperf client indicates that it is connected, but basically just sits there until I stop it with Ctrl-C: # LD_PRELOAD=$LDP_PATH VCL_CONFIG=$VCL_CFG taskset --cpu-list 4,6,8 iperf3 -c 10.0.0.71 Connecting to host 10.0.0.71, port 5201 [ 33] local 10.0.0.70 port 37502 connected to 10.0.0.71 port 5201 *VPP session info: Client side:* vpp# sh session verbose Thread 0: no sessions Connection State Rx-f Tx-f [1:0][T] 10.0.0.70:37502->10.0.0.71:5201 ESTABLISHED 0 0 [1:1][TLS] app_wrk 2 index 0 engine 1 tcp 1:0 ESTABLISHED 0 0 [1:2][T] 10.0.0.70:6875->10.0.0.71:5201 ESTABLISHED 0 0 [1:3][TLS] app_wrk 2 index 1 engine 1 tcp 1:2 ESTABLISHED 0 0 Thread 1: active sessions 4 Thread 2: no sessions Thread 3: no sessions Thread 4: no sessions *Server side:* vpp# sh session verbose Connection State Rx-f Tx-f [0:0][TLS] app_wrk 2 engine 1 tcp 0:1 LISTEN 0 0 [0:1][T] 10.0.0.71:5201->0.0.0.0:0 LISTEN 0 0 Thread 0: active sessions 2 Connection State Rx-f Tx-f [1:0][T] 10.0.0.71:5201->10.0.0.70:6875 ESTABLISHED 0 0 [1:1][TLS] app_wrk 2 index 0 engine 1 tcp 1:0 ESTABLISHED 0 0 [1:2][T] 10.0.0.71:5201->10.0.0.70:37502 ESTABLISHED 0 0 [1:3][TLS] app_wrk 2 index 1 engine 1 tcp 1:2 ESTABLISHED 0 0 Thread 1: active sessions 4 Thread 2: no sessions Thread 3: no sessions Thread 4: no sessions Thread 5: no sessions
