Site Speed Increase Addon

[Felix]

Guys,

Anyone worked with Site Speed addon for GSC?

First let's clear things up a little.

Besides GS, is GSC a new abbreviation ? Could it be: GetSimple CMS ?

What do you mean when you write: addon for GSC ?

1. addon for GSC, as you wrote it in your post  ?
2. or, addon for use in a web browser ?

Since there are no GS plugins labeled as Site Speed, nor as site speed or as sitespeed,
let me guess: addon for use in a web browser . . . .

So which addon could that be ? Mmmm  . . . how about: https://www.sitespeed.io/

So why didn't you put a link in your post in the first place ?
I think I get it . . . . it should be all obvious . . . . right ?

And no I haven't used Site Speed ever, nor have I used sitespeed.
