WebCache hit ratio is a measurement of how many content requests a cache is able to fill successfully, compared to how many requests it receives. A content delivery network (CDN) provides a type of cache, and a high-performing CDN will have a high cache hit ratio. For example, if a CDN has 39 cache hits and 2 cache misses over a given timeframe ... WebUsing four different web server logs, we show that GDS-like replacement policies emphasizing size yield the best file hit ratio but typically show poor byte hit ratio, while GDF-like replacement policies emphasizing frequency have better byte hit ratio but result in worse file hit ratio.

WebThe cache hit ratio is one of the measurements of a CDN’s cache performance. It measures the proportion of the requests to the CDN’s servers that are “cache hits”. The formula for calculating the cache hit ratio is as follows: To illustrate, let’s say that a CDN server logged 90 cache hits and 10 cache misses. WebAssume both caches have single cycle hit times Memory accesses take 15 cycles, and the memory bus is 8-bytes wide: i.e., a 16-byte memory access takes 18 cycles: 1 (send … To configure Raw logs for your Azure CDN from Microsoft profile: 1.
