(2) We also optimize the caching strategy which takes both the user's access result and cache hit ratio into account.
As verified by Pfaff et al., the overall cache hit rate of Open vSwitch was 97.7% (i.e., the value of [p.sub.1]) in a real commercial multitenant data center [15].
Compared with the result of [25] regarding the number of queries submitted by a single user to generate an obfuscation area, our cache hit ratio was 0, indicating that, without using the cache, four users or more are required to simultaneously transmit a query to meet the privacy requirements with a reduced number of pseudoqueries sent by the anonymizer to the LBS server.
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.
An expires- based cache hit is almost always faster than a validation-based near hit.
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. The value of K is initialized to one, incremented whenever the prefetch efficiency exceeds a predetermined upper threshold, and decremented whenever the efficiency drops below a lower threshold, as shown in Figure 7.
If a reuse results in a cache hit we say that the reuse is realized.
Figure 11 shows the average hit rate across all client caches for the UNIFORM workload.(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 ratio of cache hits to the number of attempts to access the cache is called the hit rate, which is the key to performance.
