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
