  1. PageCDN uses Brotli:11 compression for Open Source CDN and premium CDN.
  2. "Common Size" is the average size of compressed files served from different Open Source CDNs at the time these tests were performed. List of CDNs for each library is available in details.
  3. Columns reflect 'total transfer sizes' including HTTP headers. The actual library size after compression is even smaller.
