Why does the cache system yield faster results than the uncached? The cache system yields faster results than the uncached system because cache is much faster than main memory. Cache memory is faster than main memory as it is located on the processor chip itself. Its speed is comparable to the processor registers and so frequently required data is stored in the cache memory. [6]

Additionally, What are the advantages of using cache memory? This leads to faster execution of any process. The cache memory can store data temporarily as long as it is frequently required. After the use of any data has ended, it can be removed from the cache and replaced by new data from the main memory. Since the cache memory is quite fast, it is extremely useful in any computer system. [6]

Simply so, What are the advantages of data caching? Storage data caching has the following advantages: Latency Analytical and transactional workloads have reduced query-response time because the solid-state drive (SSD) storage has lower latencies. If you use server-side caching, the average latency for a transactional workload can be reduced by half. [4]
