known as TCP slow start. For this reason, it is very inefficient to make HTTP connections that are inherently abrupt and transient. HTTP/2 can use TCP connections more efficiently by allowing all data streams to share the same connection, allowing high bandwidth to truly serve HTTP performance gains.This single-connection multi-resource approach reduces the link pressure on the server, consumes less memory, has greater connection throughput, and improves network congestion due to a decrease in

PHP under IIS, Microsoft has given the fastcgi solution. FastCGI can allow the PHP process to be reused instead of every new request to re-open a process. FastCGI can also allow several processes to execute simultaneously.
