We have a server that is serving one html file.
Right now the server has 2 CPUs and 2GB of ram. From blitz.io, we are getting about 12k connections per minute and an
Config file:
worker_processes 4; # 2 * Number of CPUs
events {
worker_connections 19000; # It's the key to high performance - have a lot of connections available
}
worker_rlimit_nofile 20000; # Each connection needs a filehandle (or 2 if you are proxying)
# Total amount of users you can serve = worker_processes * worker_connections
