What does rendering in rails depend on?

Question

Search Engine Optimization

On the local in development, the page is rendered 3-4 times faster than on the production server in production.
As a local server - WEBrick 1.3.1. On the production server - unicorn + nginx.
On the LAN sata screw, 4GB of RAM, 4 cores. On the combat server ssd screw, 24GB of RAM, 8 cores.
We are talking about milliseconds, but they are fundamental to me. You have to enable caching of everything and everything in order to achieve the same results as on the local. I monitor the data through the meta_request gem.
So the question is - what affects rendering speed? The combat server should obviously do this more quickly.

Answer 1

Why sin on rendering? And not a bunch of unicorn-nginx?

Answer 2

as for the differences
- locally: only time to convert data to html
- on the server: time to build html + data transfer => such factors as Internet speed and channel width appear.
Are you sure that you are purely measuring page generation time?
