NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

About compression

Audio compression is used to reduce the dynamic range of a recording. Dynamic range is the difference between the loudest and softest parts of an audio signal. It was originally used to guard against defects when cutting wax and vinyl phonograph records, but generally became useful as a way of increasing the loudness of an audio recording without achieving distortion.

The goal of most compression applications is to increase the amplitude of the softest parts of a recording, without increasing the amplitude of the loudest parts.

Compressor anatomy

Compressors generally all have the same conceptual parts. However, not all compressors present variable controls for all parts to the user. If you don't see all of your compressor's controls here, there's a chance it either has a fixed value (and no control), or is named something else:
