[ovs-discuss] What is the proper memory size for OVS+DPDK

Hi All,

I am wondering to know the best memory size for OVS+DPDK. Now the DPDK is initialized by “–socket-mem=1024,0”, and I am wondering what is the best value? Why not 2048, 4096?

Appreciate to know what determines the best number (like ovs itself consume x memory, VM itself consumes y memory….)

Also, if OVS+DPDK uses more memory than the configured socket-mem, what is the behavior? Will ovs try to allocate the memory dynamically? Thanks.

Br,
Wang Zhike
