Simulation proves that, by employing the NCB algorithm, the cache hit rate can be improved obviously and the total network cost can be decreased effectively.
Web服务器插件包含内置ESI处理器，该处理器将缓存整个页以及必要的片段，具有较高的缓存命中率。
The Web server plug-in contains a built-in ESI processor which caches whole pages, as well as fragments, providing a higher cache hit ratio.
如果Opened _ tables随着重新运行SHOWSTATUS命令快速增加，就说明缓存命中率不够。
If Opened_tables increases quickly as you rerun the SHOW STATUS command, you aren't getting enough hits out of your cache.
位于因特网骨干网和同一接入网之间的流媒体缓存代理服务器相互协作，可以提高缓存命中率，保持负载平衡。
Cooperation of streaming media cache servers sited between the Internet backbone and an access network can increase the hit rate and keep load balancing.
这种缓存结构同传统的相比，缓存命中率有所提高，内存消耗变小了，同时大大改善了本地缓存空间的可管理性。
Compared with the traditional structure, it not only USES less memory, also improves the administration of local cache space.
通过实验对比，PLAC比其他位置相关缓存替换策略更为有效地提高了缓存命中率，缩短了查询平均响应时间。
The contrast experiments show that the PLAC increases cache hit rate and shortens query average response time more effectively than other location dependent cache replacement strategies.
诸如缓存大小、已使用的条目、缓存命中率和未命中率之类的统计数据以及更多的数据可以很好地概述缓存的使用模式。
Statistics such as the cache size, used entries, cache hits and misses, and many more provide a good overview of their usage patterns.
实验结果表明，静态模型的缓存命中率预测结果比实际高70%以上，而该模型则能适应负载的变动，预测结果与实际结果差别在10%左右。
The performance of the static model differs from the actual results by 70% while the performance of the dynamic model differs by only 10%.
此外，DynamicQueryMode包含一个细粒度元数据和单元数据缓存(即一个trickle fed)以及一个比以前更高的缓存命中率。
In addition the Dynamic Query Mode contains a fine grained metadata and cell data cache which is trickle fed and a higher cache hit ratio than was previously possible.
由于您在130秒内访问了Portlet，系统仍然具有有效的缓存条目(“缓存命中率”)，因此，该系统将从缓存中提供Portlet片段。
Because you accessed the portlet within 130 seconds, the system still had a valid cache entry (" cache hit "), and so it serves the portlet fragment out of the cache.
一般情况下，不鼓励在SQL中使用字面值，而是主张使用变量或参数，因为字面值会使每个语句具有独特性，这会降低缓存的命中率。
Use of literals instead of variables or parameters is generally discouraged within SQL because it makes each statement unique, which drives down cache hit ratios.
