Subject: [PATCH net-next 0/2] Performances improvement for IPv6 Segment Routing
Date: Fri, 24 Mar 2017 10:46:25 +0100 [thread overview]
Message-ID: <20170324094627.16796-1-david.lebrun@uclouvain.be> (raw)
This patch series improves the performances of IPv6 SR by optimizing skb head
reallocation and extending the use of dst_cache. The overall performances improve
by 35%.
Before patch series (SRH encap):
Result: OK: 7348320(c7347271+d1048) usec, 5000000 (1000byte,0frags)
680427pps 5443Mb/sec (5443416000bps) errors: 0
After patch series (SRH encap):
Result: OK: 4774543(c4774084+d459) usec, 5000000 (1000byte,0frags)
1047220pps 8377Mb/sec (8377760000bps) errors: 0
Baseline for plain IPv6 forwarding:
Result: OK: 4244144(c4243722+d422) usec, 5000000 (1000byte,0frags)
1178093pps 9424Mb/sec (9424744000bps) errors: 0
David Lebrun (2):
ipv6: sr: expand skb head only if necessary
ipv6: sr: use dst_cache in seg6_input
