Here are some tips on how to optimize Nginx for serving static files and dynamic PHP content.
In context of web server speed our primary metric is server response time, that is, the time it takes for the server to start sending content in reply to the visitors request. Using Apache Bench we benchmarked the server by requesting a single CSS file thousands of times in succession, and varying the count of concurrent connections.
The process for any static file is the same, so there is not much point in benchmarking many different static files. Comparing the 6 milliseconds of a static page to on average 300 milliseconds of a PHP page tells us that serving PHP is 50 times heavier and an obvious goal for our optimization. Nginx has the option to cache file descriptors, meaning that if the same file is accessed many times, Nginx will be able to fetch in faster from the file system. Also make sure that the defined path exists and the user id running the web server has write access to it.
The difference is so big, that the cached page speeds are barely visible at the bottom of the graph. In the above example the application is WordPress and there are some WordPress-specific options. Finally, to make sure that you web server stays fast and to spot any sudden changes, use some kind of monitoring solution that loads several subpages of your site at regular intervals. NetBeans requires having the Java VM installed on machine; either Sun Java 6 or OpenJDK should be installed on machine.


Step 5: The package will start the graphical installer, click next or customize the installation packages.
No matter how good your web service is, if it takes 5 seconds to load a page, people will dislike using it.
However, choosing the software is only the first step on the path to blazing fast web services. A good tool for testing just that is Apache Bench (command ‘ab’) and as it is rather old and mature, it is available from pretty much any Linux distribution’s repository. The jumps between 4000 and 5000 for the two changes reflect the point where the response time is rounded to 5 instead of 4 milliseconds. For now we’ll have both options enabled and later we should do benchmarks with different file types and sizes to determine optimal gzip usage on a larger scale. Eventually in this case setting the cache size to 100 MB was the optimal solution, as we don’t want to waste RAM either. Varnish, and with this built-in proxy feature available, there is no real need to put Varnish in front of Nginx. Still, it is the application itself that has the biggest influence of its speed and performance. CSS, image, JavaScript) and the web server only has to parse the request URI, fetch the file from the file system and send it away. This enables us to pre-compress static files (but that has to be done with another custom program).


In fact, Varnish as an extra step would only slow things down and increase point of failures. We could fine tune the settings of PHP-FPM and most importanlty we could fine tune the settings of the database server that PHP uses to store and retrieve data.
If it generates big outputs, parses and traverses complex structures, makes hundreds of database queries etc then it will stay slow.
The release also provides significant Swing GUI Builder enhancements, CSS3 support, and tools for visual debugging of Swing and JavaFX user interfaces. The second and more complex case is when there is dynamic content: the web server parses the URI, notices it’s meant for a PHP file, passes the request via FastCGI to the PHP processor.
Additional highlights include Git support integrated into the IDE, new PHP debugging features, various JavaEE and Maven improvements, and more.
The PHP processor can in turn do more complex things, like query a database for information to be included in the response. Finally when the PHP processor is done, the web server passes the result back to the browser that requested it.
