Re: Performance issue with vmxnet3 pmd

HI Guys, I will continue this thread.

On ubuntu 14.4 (Kernel 3.13) with DPDK 1.7 vmxnet3-usermap 1.2 doesn't compile.

From the git it seems to have been updated 3 months ago.

Is this project going to be killed? And should I look for different
alternatives.

Thomas,

The last time I tried vmxnet3-usermap a couple of weeks ago, it did not
compile against the latest kernel (3.11).  Is it still the case?  Or do you
have the latest version which is compatible with newer kernels?

Also, do you have any benchmark numbers with vmxnet3-usermap in any chance?

Hi,

I was testing l2-fwd with vmxnet3 pmd (included in dpdk).

Have you tested vmxnet3-usermap (http://dpdk.org/doc/vmxnet3-usermap)?

The maximum forwarding rate I got from vmxnet3 pmd with l2fwd is only 2.5
to 2.8 Gbps.

It could be interesting to know your exact testing procedure with numbers
for
vmxnet3-usermap.

Thanks
