SVR.JS - a web server software running on Node.JS can now connect to FastCGI (Fast Common Gateway Interface) servers through GreenRhombus mod! We have specifically implemented the responder role of FastCGI. FastCGI (Fast Common Gateway Interface) is an binary interface between web server and web applications. It aims to reduce overhead related to spawning new processes (as it was in CGI), allowing a web server to process more requests at the time. We did switch from PHP-CGI and RedBrick to PHP-FPM and GreenRhombus on our SVR.JS Forum. Before the switch, the server responded within 300ms. After the switch it is only 100ms! We have tested from our premises though.
