Thanks for your advice. I will definitely check whether the cloud provider
will have AES-NI or not. Could you explain a lot bit more why AES-NI will
affect the JVB's performance?

You should make sure your VMs have AES-NI. I don't believe DO have that.
Amazon and Google do though.
Thanks for your information. You are right that hosted in VMs will slow
down the performance. I did this test because I plan to host the JVB on
cloud. In this case, the servers will be hosted on VMs provided by cloud
vendor. Is it normal to host jvb on cloud based on your experience? Do you
have any existing cases that JVB can handle lots of streams?
PS, I did a simple 4 streams test on my personal VM. JVB took 60% CPU when
there are 4 steams connected. Please find my VM information below. I want
to know whether it is normal nor not. Thanks for your advice.
