How I cut GTA Online loading times by 70%

It is absolutely unbelievable (and unforgivable) that a cash cow such as GTA V has a problem like this present for over 6 years and it turns out to be something so absolutely simple.

I do not agree with the sibling comment saying that this problem only looks simple and that we are missing context.

This online gamemode alone made $1 billion in 2017 alone.

Tweaking two functions to go from a load time of 6 minutes to less than two minutes is something any developer worth their salt should be able to do in a codebase like this equipped with a good profiler.

Instead, someone with no source code managed to do this to an obfuscated executable loaded with anti-cheat measures.

The fact that this problem is caused by Rockstar's excessive microtransaction policy (the 10MB of JSON causing this bottleneck are all available microtransaction items) is the cherry on top.

(And yes, I might also still be salty because their parent company unjustly DMCA'd re3 (https://github.com/GTAmodding/re3), the reverse engineered version of GTA III and Vice City. A twenty-year-old game. Which wasn't even playable without purchasing the original game.)

The old maxim of "Premature optimization is the root of all evil" has over time evolved to "If you care one iota about performance, you are not a good programmer".

And fwiw, the full quote is:

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil.

Yet we should not pass up our opportunities in that critical 3%.

Also, it’s not “never optimise”. It’s “only optimise once you’ve identified a bottleneck”. I guess in a profit-making business you only care about bottlenecks that are costing money. Perhaps this one isn’t costing money.

Precisely. Hasn't GTA Online done over a billion in revenue?

Given how incredibly successful it's been, it's conceivable the suits decided the opportunity cost of investing man-hours to fix the issue was too high, and that effort would be better spent elsewhere.

They're making lots of money but the ridiculous load times absolutely cost them money. It's not worth an unlimited amount of dev time to fix, but they definitely should have assigned a dev to spend one day estimating how hard fixes would be.
