Caching the base page/HTML is common, and it should have a positive impact on backend times. Key things to understand from your CDN Cache Hit/Cache Miss – Was the resource served from the edge, or did the request have to go to origin? Latency – How much time does it take to deliver a packet from A to B.

This is a rough post to share this old but good case study of using these tools, and to help justify their further development. Reads usually have apps waiting on them; writes may not (write-back caching). biolatency From [bcc], this eBPF tool shows a latency histogram of disk I/O. Counting cache functions.

Each stage has its unique challenges and potential pitfalls, as other case studies show. While dynamic serving provides simplicity in implementation, it imposes significant time costs due to the computational resources required to generate the pages and the latency involved in serving these pages to users at distant locations.

To further exacerbate the problem, the 302 response has a Cache-Control: must-revalidate, private. header , meaning that we will always make an outgoing request for this resource regardless of whether or not we’re hitting the site from a cold or a warm cache. com , which introduces yet more latency for the connection setup.
