When a cache client attempts to access data, it first checks the cache. If the data is found there, that is referred to as acache hit. The percent of attempts that result in a cache hit is called thecache hit rateor ratio. Requested data that isn't found in the cache -- referred t...
However, it will increase the cache overhead. 字区大小: 贮藏所粒度。 更小的价值带来更高的性能。 然而,它将增加贮藏所天花板。 [translate] aStrategy: Chooses what kind of data is to be cached. An appropriate cache strategy will improve the cache hit rate.\r\n Read-data && Write-data: ...
The downside of mmap, however, occurs when data is not in the cache. This usually happens when the ratio of storage size to RAM size is significantly higher than 1:1. Every page that is brought into cache causes another page to be evicted. Those pages have to be inserted into and remov...

Data is always retrieved through the memory hierarchy (smallest == fastest to slowest). A cache hit/miss usually refers to a hit/miss in the highest level of cache in the CPU -- by highest level I mean the largest == slowest. The cache hit rate is crucial for performance, since every...
Cache hit ratio: Monitor how effectively your CDN is serving cached content, revealing potential optimization opportunities. Performance metrics: Track page load times and response times and identify bottlenecks for continuous improvement. The Future of CDNs CDNs continue to evolve, offering innovative...
“What cache hit rate is good for optimal MySQL Performance” is typical question I’m asked. It could by MyISAM key_buffer or Innodb innodb_buffer_pool it does not really matter. In both cases trying to come up with constant “good” hit rate is looking for trouble. Well of course yo...
One way to improve page speed is to minimize your images and other visual content’s size as they take the maximum time to load. Optimizing your cache and avoiding redirects also improves page-load speed. You can also keep a simple page design to minimize the number of HTTP requests, which...
When conducting a DNS spoofing attack, an attacker attempts to introduce corrupt DNS cache information to a host in order to impersonate that host’s domain name—for example, www.onlinebanking.com. Once that domain name has been successfully spoofed, the attacker can then use it to deceive a...
Cache is one of the most important tools programmers use to create a high-performance, high-concurrency system.
