Apache is a free and open source cross-platform web server software which is widely used. For delivery of static pages, an Apache series was rated significantly slower than Nginx and Varnish. To approach this issue, the Apache developers designed an event, which mixes the use of several processes and several threads per process in an asynchronous event-based loop. This architecture accommodates better performances. Nginx and Varnish can be used as plugins in Apache, meanwhile, there are cPanel based combination plugins created to enhance performance.
Nginx: It also has features like caching, security and load balancing. Caching done by Nginix is mostly static. Load balancing keeps check of the network traffic.
Varnish: The uniqueness of Varnish is the dynamic caching. The process of caching can be done to reduce data access time. It also helps with the recovery of input/output which in turn enhances application performances. Dynamic page caching helps in caching of HTML pages considering the cookies, request headers etc. How and when to cache the responses are decided upon by making use of a mix of factors from an HTTP request. Varnish supports load balancing and caches feature Gzip compression and decompression, HTTP Streaming Pass and Fetch, etc.
Now let's have a look on to few performance boosters which make use of features of Nginx and Varnish.
Apachebooster is a cPanel plugin built to improve the total execution of a server by raising the performance of Apache Software. Compounded with Nginx and Varnish Apachebooster doubles the working volume and capacity of Apache Software which in turn helps the servers to become faster in their processing. Compared to other plugins in the industry ApacheBooster has the advantage of Nginx and Varnish together. Apache software has many valuable properties, which may require manual aiding, usually done by an expert. Apachebooster can work for it out of the box.
In short, When a user reaches the site over HTTPS protocol, Nginx sends the request to Varnish and if Varnish already has the content in its cache it immediately responds with that content. Else, Varnish requests the content from Apache (if necessary), caches it and then assigns the content to Nginx. Nginx encrypts the content and transfers it to the user. Just like the caching, image optimization, minification of JS and CSS are also done by Apachebooster. Last but not the least feature is the SSL technology for security. It is the most trusted and safe technology implemented in HTTP.
Apachebooster requires a simple installation procedure only. The number of advantages of Apachebooster is inversely proportional to the cost you give. Because it's worth buying and you get an unexpected number of advantages.
Engintron is Nginx on cPanel. Nginx functions as a web traffic proxy, directly serving all static contents like CSS, JS, images by default instead of Apache. This drops appreciably the CPU/RAM resources used by Apache, leaving your server with more space with room for more websites to host. Engintron will raise the performance and web serving capacity of the server while decreasing CPU/RAM load at the same time. It does that by installing and configuring the conventional Nginx web server to operate as a reverse caching proxy for static files (like CSS, JS, images, etc).
cPnginx is again an Nginx highlighted plugin. Nginx doesn’t rely on threads to manage requests. Rather it uses a much more scalable event-driven (asynchronous) architecture. This architecture uses small, but more importantly, expected amounts of memory under load. Likewise, if you don't demand to handle thousands of synchronous requests, you can still avail from Nginx's high-performance and small memory footprint.
There are so many plugins available nowadays, X-Varnish, Nginx Admin (NginxCP) are few other similar plugins. Website performance optimization is perpetually something that should be the top priority, especially when there is so much competition. The web is growing at an active pace, and this year we have seen some severe changes to web performance, such as the release of HTTP/2 and on-page assets extending to gain in size. Some studies show that in two years global Internet traffic will be equivalent to 66 times the volume of the whole global Internet 10 years before. So choose your performance boosters wisely!
