The way to improve the cache memory performance is to improve the cache hit
The evaluation results showed that TBF achieves a better cache hit
rate and operations per second comparable to those of LRU in spite of its much smaller memory requirements (Cristian et al.
If a cache hit
occurs, the reference bit is set to 1.
The results we obtained for the cache hit
ratio under different cache sizes are displayed in Figures 2, 3 and 4.
Thus, when a response varies on the User-agent header we can only get a cache hit
for clients running the exact same version of the browser, on the same operating system.
Although local client caches are effective, the performance of a distributed file system is often limited by the poor server cache hit
rate [Dahlin et al.
Prefetch efficiency is defined to be the ratio of useful prefetches to total prefetches where a useful prefetch occurs whenever a prefetched block results in a cache hit
If a reuse results in a cache hit
we say that the reuse is realized.
14) As can be seen in the figure, the avoidance-based algorithms all have higher client cache hit
rates than C2PL.
Similarly, when the data are already in the cache, it is called a cache hit
The key performance metrics of Cassandra monitored by Applications Manager include heap size and usage, garbage collection, IO wait, cache hit
rate and compaction count.
We conduct simulation experiments to validate the effectiveness of our proposed SCD algorithm, and numerical results indicate that the proposed solution can effectively increase cache hit
rate, reduce outbound traffic and content delivery latency compared with existing caching strategies.
