Check if your web server supports Brotli Compression

Brotli is a new compressed data format developed by Google for compressing web data. It is documented in RFC7932. Currently, almost all modern web browser support Brotli which compressed better and faster than Deflate.

Brotli is can be enabled in most popular web server including:

  • Apache HTTPD – through mod_brotli (for release after 2.4.26)
  • Nginx – ngx_brotli (provided by Google)
  • Node.js (trough shrink-ray module
  • LightSpeed (since version 5.2)
  • Microsoft IIS (through IIS-brotli extension, for IIS 7.5 and above)

Testing for Brotli Support

KeyCDN.com has provided a tool for testing whether your website supports Brotli compression.

You can go over the website and get your server tested. For nginx webserver, ngx_brotli will automatically downgrade to gzip if the browser does not support brotli encoding

 

Find largest file in Linux server using “du”

Short on diskspace? You can use ‘du’ to find largest files in your linux server using ‘du’ tool.

 

du --total -sh /path/*

Additionally you can also include a ‘threshold’ parameter to list only file larger than the unit which you’ve specified, by using “-t” parameter.

Example, list files larger than 100MB

du --total -sh -t100M /path/*

You can use “M” for megabytes, “G” for gigabytes and “P” for Petabytes. Positive number denotes files must be at least the specified size. Negative number means the files must be at most the specified size.
