more appropriate to explain the high pressure).

I don't follow this part. Why can't the server control however it wanna
control?

Hi,

Do you agree that the server can't control how many io it can receives
from one client if we limit from server? I think the difference is that
limit from client can control it...

Thanks,

Thanks.
