Most performance issues aren’t in your code… and it took me too long to accept that

For the longest time, every time something was slow, i assumed: “my code is inefficient” so i’d start optimizing logic, refactoring functions, etc. but after working on a few real systems, i’ve noticed a pattern: a lot of the time the issue is actually: • network calls • database queries • third-party services • unoptimized assets not the core code itself now i try to measure first before touching anything curious if others had the same realization or is it just me? submitted by /u/OliverPitts [link] [comments]
