[dpdk-users] IPSEC-SECGW - type no-offload huge latency

I see that the delay is derived from the MAX_PKT_BURST
If I decrease it, the delay decreases accordingly. And we always transmit a burst of pkts (==MAX_PKT_BURST)
But this behavior is wrong because we should transmit if there are ant pkts ready for tx.
I suspect that the delay is in the ipsec_dequeue logic ...
Any idea ?
Best Regards
