Performance terms
Every millisecond matters — here is how to win them back
Slow software costs money, loses users, and erodes trust. Performance engineering covers profiling, caching strategies, database query optimisation, network latency, memory management, and the architectural patterns that keep systems fast under real-world load. Most performance problems are invisible until they are not — these terms help you find and fix them before your users do.
