Hi everyone, wishing all a happy new year .
I have a question regarding Tiered Caching:
- This topic/post basically verifies my understanding that with Tiered Caching uncached visitor requests pass two Cloudflare servers, the lower-tier serving the visitor and the upper-tier pulling from the origin. Without Tiered Caching uncached requests could involve a single Cloudflare server only which pulls from the origin and serves the visitor.
- So the immediate question that came to my mind is whether this has a negative impact on how fast the visitor receives uncached data and hence sees the web page.
- In case the data is cached by the lower-tier, of course nothing changes.
- In case the data is cached only by the upper-tier, I can only assume that Cloudflare is able to internally transfer faster from upper-tier to lower-tier, compared to pulling from origin, so in this case there should be a performance benefit for the visitor, at least no downside.
- But there are naturally resources, notably dynamic web pages (e.g. PHP), which cannot or should not be cached at all, which would unnecessarily pass two Cloudflare servers every time, at least from overall efficiency and performance point of view.
- Or is the internal transfer so fast that it generally has an insignificant effect? Did anyone already do some benchmarks or analysis about this?
