Dear Rubina, During the development I did some ad-hoc for up to 4 cores (since that was the h/w I have), it seemed reasonable - but obviously there is something that I did not spot during my tests.
It's hard to say what is going on without looking in more detail. --a On 5/9/18, Rubina Bianchi <r_bian...@outlook.com> wrote: > Thanks for your prompt response. > If it would be possible I want to know about the maximum throughput which > you take from vpp in stateful mode (permit+reflect acl rule, session table) > ? > > Does vpp work scalable?
