We introduce least hit density (LHD), a novel eviction policy for key-value caches. LHD predicts each object’s expected hits-per-space-consumed ...

Witryna19 mar 2024 · Less good: cache hit rate shouldn’t increase much either. On the other hand, we also found that a significant portion of these requests are images, which could potentially take up lots of disk space and hike up cache eviction rates. Enough napkin math - we needed to start assessing real world data. A/B testing: caching the queries Witrynaand studied the impact of the window size on the cache hit rate and throughput. An orthogonal approach for improving cache coherency is to exploit peering among MSs [10]. In this approach, called Peer Enhanced Cache (PEC), MSs utilize the ad-hoc mode of operation, which is now available with most wireless interfaces.

A higher hit rate indicates fewer read operations on disks and therefore lower I/O latency. Conversely, a lower hit rate indicates that most data being read is fetched from disks, where response
WitrynaThe set-associative cache generally provides higher hit rates than the direct-mapped cache because conflicts between a small set of locations can be resolved within the cache. The set-associative cache is somewhat slower, so the CPU designer must be careful that it doesn’t slow down the CPU’s cycle time too much.
