CloudFlare 對 Brotli 的測試

之前有提過這件事情,由於 Firefox 已經支援 Brotli 了 (Google 推出 Brotli 無損壓縮法),所以 CloudFlare 的人整理了目前的效能比較:「Results of experimenting with Brotli for dynamic web content」。

主要還是 Brotli 拿了不少資源來換壓縮率,對於 static content 由於可以事先算好而大勝不少 (大約可以再榨出 15% 的壓縮率,從 zlib 9 的 27.7% 降到 brotli 10 的 23.3%):

The current state of Brotli gives us some mixed impressions. There is no yes/no answer to the question "Is Brotli better than gzip?". It definitely looks like a big win for static content compression, but on the web where the content is dynamic we also need to consider on-the-fly compression.

另外對於大檔案、網路速度不快的連線來說也頗有幫助,但對於 on-the-fly 的壓縮反而會比較慢。
