Hi, Daniele,
I am also interesting in profiling the ovs process and would like to
participate in the discussion.
I am using oprofile-1.1.0 to profiling the ovn-northd process. I believe
oprofile-1.1.0 share the same underlying profiling mechanism as Linux perf
(correct me if I am wrong). However

Hi,
In our scalability test for OVN, we observed an in-scalable behaviour of
the
ovn-northd process: the time binding a logical port increases as # of large
port increasing, regardless of whether logical ports belong to the same
logical
switch. The most suspicious function in causing this issue is

I am studying the hashing functions in OVS and find these two
implementations: hmap and cmap. I understand that cmap is the improved
cuckoo hashing and cmap supports multiple-reader and single writer. My
questions are:
1. What does hmap stand for? hash map?
2. hmap looks much
