LAMP Stack, with Apache
LEMP Stack, with nginx
Apache:
-Has been available for so many years (since 1995), a lot of users and modules (mostly open-source) written to expand its functionality;
-Process/thread-oriented approach — slows down under heavy load, need to spawn new processes and consuming more RAM, also creates new threads which have to compete for CPU and RAM resources;
-Limit has to be set to ensure that resources are not overloaded, when the limit is reached, additional connections will be refused;
-Limiting factor in tuning Apache: memory and potential to dead-locked threads contending for the same CPU and memory.
nginx:
-Open source web server application written to address performance and scalability issues associated with Apache;
-Event-driven, asynchronous and non-blocking approach, doesn’t create new processes for each web request;
-Setting number of worker processes, and each worker can handle thousands of concurrent connections;
-Modules are included at compile time, have internal PHP code compiler (no need for PHP module)
To conclude, nginx is faster and able to handle much higher load compared to Apache using the same set of hardware.
