FastOrSlow – the new site checker from WordFence

Today the Wordfence developers announced the new fastorslow.com tool, a handy tool for seeing how fast your site is in various parts of the world. The Wordfence folks build a quite useful plugin used by many sites – and this one – to keep reduce risk of attack.

This new tool however can be used to see the performance of any type of public site and recommendations on speeding it up. It also would be a much easier way to time requests to a server like in the World Network Requests Measurement post.

One thing you might wonder is, how is it requesting these and what is it coming from? Go to your server logs and you can see what and where it is requesting from:

cd /var/log/nginx
sudo tail -f ./access.log

when a FastOrSlow runs, you will see something like:

Looking at the user-agent it looks like this is using the Chrome Lighthouse tool to make recommendations – and the originating IPs are from Defiant (surprise surprise, the company that makes Wordfence):

host 45.79.45.44
host 104.207.154.109
host 172.105.213.76

I can see this as being a very handy tool, more so than the common https://downforeveryoneorjustme.com/ that many use from time to time. It can not just show you how fast your site is, but can show you where a site’s server is based from the speed to transfer in various regions.
