Byte hit ratio

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.
