Hi Everyone,
I would greatly appreciate any input.
The setting that i am working with is a host with ovs-dpdk connected to a
VM.
What i see when i do performance test is that after about a minute or two
suddenly i have many drops as if the cache was full and was dumped
improperly.
I tried to play with the settings of the n-rxq and n_txq values, which
helps but only probably until the cache is filled and then i have drops.
The things is that sometimes, rarely, as if by chance the performance
continues.
My settings is as follows:
OVS Version. 2.6.1
DPDK Version. 16.07.2
NIC Model. Ethernet controller: Intel Corporation Ethernet Connection I354
(rev 03)
pmd-cpu-mask. on core 1 mask=0x2
lcore mask. core zeor "dpdk-lcore-mask=1"
Port "dpdk0"
Interface "dpdk0"
type: dpdk
options: {n_rxq="8", n_rxq_desc="2048", n_txq="9",
n_txq_desc="2048"}
ovs-appctl dpif-netdev/pmd-rxq-show
pmd thread numa_id 0 core_id 1:
isolated : false
port: dpdk0 queue-id: 0 1 2 3 4 5 6 7
port: dpdk1 queue-id: 0 1 2 3 4 5 6 7
Thanks,
Michael
