On the Effects of Content Compression on Web Cache Performance

Compression is widely used to reduce data transmission costs, but its impact on the performance of network entities such as web caches has not yet been studied. In this paper, we evaluate the impact of compression on cache performance when the cache compresses content and the client decompresses it. We further determine the performance bounds by benchmarking the best-case (server compression-client decompression) and the worstcase (cache compression and decompression) scenarios. Our results show that caching compressed content significantly improves the cache’s hit ratio, reduces user latency and increases cache throughput. With a compres
