Worked example

Inputs

Requests per day
10000000 requests
Uncompressed header bytes
1200 bytes
Measured compressed header bytes
180 bytes

Expected results

Raw daily header volume
12 GB
Daily transfer reduction
10.2 GB

How to use this tool

  1. Enter requests per day, uncompressed header bytes, measured compressed header bytes in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "requests": 10000000,
  "raw": 1200,
  "compressed": 180
}

Accuracy and scope

Uses measured per-request averages; not a simulation of HPACK or QPACK dynamic tables.
