Performance Optimization
Noun · Development
Definitions
The iterative process of identifying bottlenecks through profiling and measurement, then applying targeted changes — such as algorithmic improvements, caching, reducing allocations, or parallelizing workloads — to improve speed, throughput, or resource efficiency.
In plain English: Making software run faster or use less resources by finding the slowest parts and improving them.
Example: "The biggest performance optimization was replacing the O(n²) nested loop with a hash map lookup, cutting the import from 40 minutes to 8 seconds."
