Hi, I didn't test this patch yet. Bhanu, could you please describe your test scenario and performance results in more details. It'll be nice if you provide throughput and latency measurement results for different scenarios and packet sizes. Latency is important here. About the patch itself:

[ovs-dev] [PATCH] netdev-dpdk: Use intermediate queue during packet transmission.

2016-12-16 Thread Bhanuprakash Bodireddy
In exact match cache processing on an EMC hit, packets are queued in to batches matching the flow. Thereafter, packets are processed in batches for faster packet processing. This particularly is inefficient if there are fewer packets in a batch as rte_eth_tx_burst() incurs expensive MMIO write.
