TurboBench: Dynamic/Static web content compression benchmark

[powturbo]

file html8 : 100MB random html pages from a 1m Alexa Top sites corpus. Number of pages = 1178 Average length = 84886 bytes The pages (length + content) are concatenated into a single html8 file, but compressed/decompressed separately using the multiblock mode in TurboBench.

compress: page1,page2,...pageN decompress : Page1,page2,...pageN

In the speedup (see below) plots you can see the best compressors for content providers:

• brotli 11 is best for static content
• brotli 5 is best until 1MB/s network transfer speed
• libdeflate 6 is best from 1MB/s to 6MB/s (followed by brotli,4)
• igzip 1,2 is best for very fast networks > 10MB/s

Remarks:

• Note that for web-content, the difference in decompression speed between zlib, brotli and others is practically imperceptible to the user.
• Actually there are only web server support for zlib, zlib_ng, slz and brotli.
• zstd is included only as reference as it is not compatible with web content encoding.

Unlike other benchmarks on the net, this is pure memory benchmark without any additional (http) server overhead.

Page Statistics: Page Length: Minimum = 16kb, Maximum = 128kb
