Subject: Re: [dpdk-dev] [PATCH] examples/l3fwd: support separate buffer pool per	port
Date: Mon, 8 Apr 2019 06:10:10 +0000	[thread overview]
Message-ID: <AM6PR08MB37824CB5348CDD4451DEAE7F9E2C0@AM6PR08MB3782.eurprd08.prod.outlook.com> (raw)

Hi Shreyansh,

I tried this patch on MacchiatoBin + 82599 NIC.
Compared with global-pool mode, per-port-pool mode showed slightly lower performance in single core test.
In dual core test, both modes had nearly same performance. 

My setup only has two ports which is limited. 
Just want to know the per-port-pool mode has more performance gain when many ports are bound to  different cores?

Used commands:
sudo ./examples/l3fwd/build/l3fwd -c 0x4 -w 0000:01:00.0 -w 0000:01:00.1 -- -P -p 3 --config='(0,0,2),(1,0,2)' --per-port-pool
sudo ./examples/l3fwd/build/l3fwd -c 0xc -w 0000:01:00.0 -w 0000:01:00.1 -- -P -p 3 --config='(0,0,2),(1,0,3)' --per-port-pool

Regards,
/Ruifeng
