We’ve been running Nginx for sometime powering a fairly high traffic
website. The single box, dual CPU (dual core) has been serving us well
but its time to upgrade. I’ve got a new system configured, quad CPU
(quad core) = 16 cores (plenty of RAM) and CentOS. My understanding is
that even though there are 16 cores, more than 5 Nginx instances will
not greatly improve performance.
I decided to benchmark the system using a single Nginx instance and
default configuration with a static html file. Using “ab” (locally)
with 50,000 connections and 1,000 concurrent ones I get around 10K
requests / second.
What particular parameters should I look into adjusting to try to double
that number? (Nginx and OS).
What is considered top performance for a single box / instance?
