As a page speed addict, I thought I’d share pagespeed tool I wrote called gitools.sh. It’s a shell script which will allow you to run via SSH command line or cronjob API queries to 3 page speed tool services listed below:
- Google PageSpeed Insight API
- GTMetrix API
- Webpagetest.org API
And send results optionally to custom Slack channel.
- As Cloudflare’s edge caches are geographically dependent on being populated by local visitors respectively, it means you need have visitors to each of the geographic locations.
- Using gitools.sh Webpagetest.org API comes in handy for this task for a select few geographic WPT locations you can test. I usually setup a cronjob and send results to my custom slack channel once a week. It will then populate the caches for each of the corresponding Cloudflare edge servers for those regions.
example running WPT API cable 5mbps tests against domain.com
./gitools.sh wpt https://domain.com dulles cable
./gitools.sh wpt https://domain.com california cable
./gitools.sh wpt https://domain.com frankfurt cable
./gitools.sh wpt https://domain.com singapore cable
./gitools.sh wpt https://domain.com sydney cable
./gitools.sh wpt https://domain.com dallas cable
./gitools.sh wpt https://domain.com london cable
./gitools.sh wpt https://domain.com tokyo cable
./gitools.sh wpt https://domain.com mumbia cable

If folks have other ways to pre-warm the Cloudflare geographic caches, you can share you tools and know how in this thread too
