How to Monitor CMS Performance
IntermediateQuick Answer
TL;DR
Monitor CMS performance with two complementary approaches: real user monitoring (RUM) to capture actual visitor experience, and synthetic monitoring to catch regressions before users do. Track Core Web Vitals via Google Search Console and Vercel Analytics, run Lighthouse CI on every deploy, monitor CMS API response times and error rates, and configure alerts so regressions surface immediately rather than after complaints.
Key Takeaways
- Real user monitoring (RUM) captures actual performance across real devices and networks — not lab conditions
- Synthetic monitoring with Lighthouse CI detects regressions on every deploy before users are affected
- Monitor CMS API response times and error rates separately from frontend metrics
- Set up automated alerts — performance regressions discovered via user complaints are already costing you
