Performance Optimization

Cache Hit: Successful Data Retrieval from Cache
A Cache Hit occurs when the data requested by a program is found in the cache memory, thus eliminating the need to fetch data from slower storage.
Cache Memory: High-Speed Data Access for CPUs
Cache memory is a small-sized type of volatile computer memory that provides high-speed data access to a processor. It stores frequently used instructions to enhance computing performance.
Cached Content: Data Stored Locally for Offline Access
Cached content refers to data stored temporarily on a local device or server to optimize performance and enable offline access. This process helps to reduce loading times and conserve bandwidth by storing copies of frequently accessed information.
Denormalization: A Performance-Enhancing Database Technique
Denormalization is the process of intentionally introducing redundancy into a database to enhance performance. This technique often involves consolidating tables and pre-joining data to reduce the complexity and time required for read operations.
Efficiency Variance: Measures the efficiency of resource usage
Efficiency Variance measures deviations in resource usage by comparing the difference between expected and actual efficiency, thereby helping organizations optimize performance and reduce costs.
Memory Leak: A Situation Where a Program Does Not Release Reserved Memory
A Memory Leak occurs when a computer program incorrectly manages memory allocations, leading to decreased performance or system crashes. It happens when the program reserves memory that is no longer needed but fails to release it.
