Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Many web servers can compress files in gzip format before sending them for download, either by calling a third-party module or using built-in routines. To enable compression, configure your web server to set the Content-Encoding header to gzip format for all compressible resources. You can also use deflate, which uses the same compression algorithms, but it is not widely used, so we recommend gzip. If streaming compression imposes too much load on your server, you can usually configure it to pre-compress files and cache them for future downloading.
Note that gzipping is only beneficial for larger resources. Due to the overhead and latency of compression and decompression, you should only gzip files above a certain size threshold; we recommend a minimum range between 150 and 1000 bytes. Gzipping files below 150 bytes can actually make them larger.
