If you have enough RAM it’s not too hard to handle 1M or more connections on linux. These guys handled 10 million connections with a java application on a single box using regular CentOS kernel with a few sysctl tweaks: sysctl -w fs.file-max=12000500 sysctl -w fs.nr_open=20000500 ulimit -n 20000000 sysctl -w net.ipv4.tcp_mem=’10000000 10000000 10000000′ sysctl … Read more
