Using up-to-date e.g. G-WAN web server and/or 10 GbE NICs to bury e.g. NGINX and/or node.js
The cloud isn't cheap and servers are coming out with ever more CPUs and faster NICs. Should we be investing in technologies which promise millions of network operations per second per server instead of n,000 network operations per second as with 'legacy' technologies such as NGINX or node.js ?
