@Matteo Thanks, but as I am still at the beginning of this, I will need to
find a way to simulate lots of users, and to find a way to profile
performance, then I can decide what to do, if you can help me how to
simulate virtual users and how to profile performance of my node app in
real time, it will be a great help!
@Mat you said ("load" should be divided by number of CPUs) isn't load
automatically divided when I node cluster?
Kind Regards,
Samir
