Memory optimization tips for performance-critical applications

[Joshua_B]

I'm working on an application where memory usage is becoming a concern. What memory optimization tips do you have for keeping applications lean and efficient? I'm particularly interested in practical advice that goes beyond the basic "don't create unnecessary objects" guidance.

For memory optimization tips, profile before optimizing. Use tools like Valgrind, Xcode Instruments, or Chrome DevTools memory profiler to find actual leaks and hotspots. Most memory issues come from a few specific places - holding references too long, caching everything, or not understanding your language's memory model. Also, learn about object pooling for frequently created/destroyed objects.

Understand your data structures' memory characteristics. An array of structs vs array of pointers can have huge memory implications. Also, be careful with strings - they're often much heavier than you think. In performance-critical applications, consider using string interning or flyweight patterns. And lazy loading - don't load everything upfront if you don't need it.

Memory optimization isn't just about using less memory - it's about using memory efficiently. Cache locality matters more than total memory usage for performance. Keep related data together. Also, pay attention to memory fragmentation over time. Some languages have better tools for this than others. And remember: the best memory optimization is often to not store something at all.
