A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot. Cache hits are served by reading data from the cache, which is faster than recomputing a result or reading from a slower data store; thus, the more requests can be served from the cache, the faster the system performs</span></span><span style="background-color: white; color: #222222; font-family: verdana, geneva, sans-serif; font-size: 15px; line-height: 26px;">.</span></div>
