How to measure time spent on response compression for Nginx?

Server NGINX
1

Hi folks:

We want to measure how long Nginx takes to compress certain response
with Gzip format. Is there any way/tool to get accurate timing?

Thanks,
-Wei

You can find some information about gzip on Calome.Org website.
