[dpdk-dev] [PATCH v2 0/3] Increase default RX/TX ring sizes

2018-01-12 Thread Kevin Laatz
Increasing the RX/TX default ring size to 1024/1024 to accommodate for faster NICs. With the increase of number of PPS, a larger RX buffer is required in order to avoid packet loss. While a ring size of 128 may be large enough for 1G and possibly 10G NICs, this is not going to scale to small packet
