It was an eventful March at Kernl, so without further ado let’s dive in!
Features, Infrastructure, & Bug Fixes
- All application servers have been upgraded to use AMD Premium droplets on DigitalOcean. These have better performance characteristics than the regular droplets and should make Kernl’s performance more consistent.
- The licensing
/validate-with-domainendpoint now includes the
expiresfield and the product UUID.
- The high-traffic
updateroutes (the ones that WordPress calls to see if any new updates are available for plugins/themes) received some performance tweaks. We saw ~20ms performance gains.
- Kernl now supports banners!
- Analytics event tracking now uses a Redis queue to shuffle events from Kernl to Kernl Analytics. Prior to this, Kernl would make a backend API request to Kernl Analytics on every request. This caused performance degradation in cases where traffic was burst-y.
- Documentation has been added for load testing if your WordPress site is behind Cloudflare.
- Kernl, Kernl Analytics, Kernl Load Testing, and RoboSwarm are now all using a managed Redis instanced provided by DigitalOcean.
- Kernl Load Testing and RoboSwarm are now using a managed PostgreSQL instance provided by DigitalOcean.
- All static files for Kernl are now hosted on Vercel (global CDN).
That’s it for March! Have a great April.
