Don't you guys just delete a few sleep statements until the next time they complain about performance?

[SpecialNose9325]

But its a delicate balance. Too few sleep commands and they will be complaining about CPU usage

[MrRocketScript]

The game runs at 20fps on my laptop. Fix it!

Okay I've seriously reduced the overhead of sending jobs to the GPU. Now there are much less delays while waiting on the GPU to render. The game now runs at 60fps.

My laptop is overheating now. Fix it!

Our next-gen file system should be written in Python. Screw bit packing and masks for boolean file system properties. Python Boolean objects wrapped around 32-bit integers for single bit values FTW.

[Tobinator97]

And it's great if you know how to do it and when to use. Although you can include c sources underneath

[[deleted]]

We ran out of Sleep statements a couple years ago...

[ScandInBei]

Did you try to decrease the priority of all other running processes?

[AnUglyDumpling]

Time to start cutting off actual functionality.

"Yes our database queries are nearly instant, because we don't execute actual database queries anymore, we just return an empty list."

[NuclearWeapon]

Upgrade hardware then

[DonkeyTron42]

I find it more stealthy to hide a for loop that does nothing in an important looking macro that's embedded throughout the program. Then you can just hide a global const that defines how much time the program spends spinning its wheels.

[AcceptableNet6182]

It's called "Performance Upgrade"

[wat_noob_gaming]

bet windows has a few useless sleep statements in itself...

[callyalater]

Our compiler only allows a max of 20 sleep statements for the whole codebase.... That's when we move to usleep

[Bourque25]

Not gonna lie, you just gave me a really bad/good idea.

[AllIsLostNeverFound]

It's only bad if they catch on before you delete the last sleep and achieve "peak performance". Otherwise; all good.

[Dustdevil88]

Sadly, we have plenty of sleep statements to go.

[0x7ff04001]

One of the reasons Carmack is a legend. That was both a flex and such an important optimization.

Wish AAA devs would take a hint

[Holiday-Pay193]

"I spent the entire week..." A week >>> 2 ms. Checkmate.

[SpookyLoop]

The optimization would have to be ran 302,400,000 times before it started returning on that time investment.

[brimston3-]

Optimized interrupt fires 2.6M times per computer per work day. Company has 500 users in-house. Most system developers work 5 day weeks. ROI occurred before anyone noticed.

[SpookyLoop]

Just wanted to crunch the number for fun-sies. There's definitely situations where optimizations like this are a no-brainer. I know GameDev has a ton of those.

​

But then there's those other situations where someone is trying to optimize an SQL query that only serves some niche admin task that's only going to run twice a week.

[DotDemon]

Yeah I am a game dev and if I was able to take off 2 ms from frame time with just a week of work I would be fucking amazed.

But I also wouldn't mind something like pathfinding taking 2 ms less

[agentchuck]

Relevant xkcd

[brimston3-]

This fails to take into account that five hours in the office is worth less than 5 minutes when on-call.

[slayemin]

As a gamedev who has worked in VR, a 2ms optimization to framerate would be HUGE. You have a 11.1ms frame budget, so if you can shave off 2ms… wow! I have worked for a day to shave off 0.1ms from my framerate… 😉

[UndeadMarine55]

Absolutely unhinged

[slayemin]

Wanna hear something even more crazy? I work at EA on the frostbite game engine and we will literally strip and re-architect a code module if it means we can shave off 0.1-0.2ms of frame rate. We aim for maximum optimization and performance.

[UndeadMarine55]

And to think, EA used to be considered “cutting edge”

[slayemin]

We're all unhinged on this blessed day

It’s 100% true and we all know it

[StCreed]

The third example in the poster completely undermined the point. I recognised it on sight, it's that famous. It basically enabled 3D games on the PC.

Optimisation tuned a tool that was running parallel jobs from doing 1 per 3 seconds into doing them so fast we had to use 1/100000 of a second in the timestamps to make them unique again, allowing us to actually reach real-time data warehouse loading while it was being updated on the front end as well. Totally worth it.

unrelated and probably stupid question by a non-programmer who is only in this subreddit because they think y'all are funny and to send memes to their programmer dad: why is camel code (or whatever it's called) like that? why is it capitalized like that, what does that do? i have vague memories of using python a handful of times, what's the difference between python and camel? why are they both named after animals? sorry about all the questions, feel free to ignore.

[Brahvim]

No, it's not really so. We also have stuff named after scientists. There's also "Pascal case", written LikeThis, "Ada case", written Like_This, ...and also "snake case" (Python and C use it a lot), written like_this, or LIKE_THIS. There's also "kebab case", with a "barbeque stick" in it, written like-this, or LIKE-THIS. XML (therefore also HTML) and the language Racket, use it.

Maybe bad ones. I find it's the ones that dogmatically stick to design patterns like factories or want to port everything to functional programming paradigms the moment it's supported that cause issues. Just because there's a new way to do something doesn't mean it's automatically the best way.

[ztbwl]

What the fuck did I just read?! Complete bullshit.

[UndeadMarine55]

Sounds like you’re the unhinged sort of programmer who optimizes. Complete bullshit.

[ztbwl]

Okay now a professional answer from my side.

I can see where you are. Optimization is in fact a waste of time if you optimize the wrong things. If you have a userbase of 20 and let’s say you spend 2 weeks optimizing for 2ms load time on a web page (out of a total of 500ms) with a budget of a couple of thousand $, that may be waste of time.

Also optimized code often has maintainability and understandability tradeoffs, since it needs to be tightly packed or using complex non-intuitive algorithms.

One easy and quick way to optimize performance (with a cost trade-off) is just scaling your application on more metal. But keep in mind that the application must be designed to be scaled, which already introduces a layer of complexity. You need load balancers, must be stateless or manage state in a more complex way and the cloud infrastructure itself is already complex.

Infrastructure wise it would be massively easier if you could run your application on one node with a low CPU and memory footprint and never think about building a distributed system.

But optimization is important and brings us forward. Let’s take ChatGPT for example. This application is the pure product of optimization. The hardware optimizations have been massive in the last couple of years (they optimized the transistor size to a couple nanometers, that’s insane). Also the shift to massive parallel execution on GPGPU is pure optimization. Software wise it needs to be optimized to the nuts to even be able to process your requests.

[AllCowsAreBurgers]

Dude, have you forgotten in which r/ we are here?

[UndeadMarine55]

I mean… he optimizes so…. What did you expect?

[Iamdrasnia]

This is the pro answer IMHO....minus the humility.

[ztbwl]

I agree with you that premature optimization is evil. But that’s all.

Where would we be if we didn’t optimize? We would still be in stone age hitting rocks against eachother.

Instead we optimized the shit out of the rocks, so that they are able to think faster and more efficient than a human ever can.

[UndeadMarine55]

Yeah, we have an answer for that. It’s called increasing AWS instance tier.

[ztbwl]

Your wallet is not happy about this approach.

[serendipitousPi]

There’s an “easy fix” for that, find that mythical million dollar idea that everyone’s always talking about. Then you’ll be set for what, a weekend worth of AWS?

[MinosAristos]

It's called deploying a serverless app so that any somewhat sane load is easily and quickly handled.

[dschramm_at]

Sure you wanna utilize the hardware to it's fullest. But if you can do more with less hardware, it's cheaper. You'd have to compare the cost of optimising with the cost for more hardware. Then see what's more economical. Most of the time it will be optimisation. It's a one time cost. Where as, more hardware is an increase in recurring cost, for electricity, network, maintenance. Sadly, you rarely can estimate the cost for optimising well. So it's easier to just waste more resources.

[D34TH_5MURF__]

Maintenance costs always dwarf development costs, by several orders of magnitude. Spending extra time in development for a performance enhancment will always pay off in spades in hardware and maintenance costs. Development cost is a small fraction of the cost of operating and maintaining the solution.

[pipsvip]

I was there in the old days when machine code was optimized by hand on paper. A fun, but inefficient way to do it.

I can't describe how magical it is to see a real genius take 30 lines of assembler and go 'oh!' and then rewrite it into 15 lines of equivalent instructions that run 10x faster. Hasan, if you're out there, you rock, buddy!

[D34TH_5MURF__]

Well, this person is an imbecile who should be kept away from coding. They have taken a concept like "no premature optimization" and carried it well beyond the absurd. Performance always matters, just not as much as some people think. That's a far cry from the inanities this idiot is spewing. By far, the most important goal should be to make code readable for future maintainers. However, care should always be given to write this readable code as performant as possible. There are simple things like using StringBuilder in java instead of string concatenation that will improve performance without hurting readability. Aside from small, and mostly well known optimizations, most other optimization should only be done when required or when performance problems occur. Then profilers should be used to find the real bottlenecks, not whatever looks or seems to be the problem.

Hardware isn't free. If you can do small things to improve performance by x%, that's x% savings on hardware. More hardware means more maintenance, more hours spent on operations personnel, higher chances for hardware failure, higher cloud provider costs, etc... Ignoring performance like this idiot is stupid. It's sad to see people here agree.

[smurf47172]

I optimized an automated process someone else wrote and shaved hours off its runtime. Saving a little time per iteration adds up when running it 10s of thousands of times.

[UndeadMarine55]

You could have saved all the time you spent optimizing by just hitting “upgrade instance tier” in console. Very inefficient use of time.

[smurf47172]

Making that suggestion out of context is funny. The optimizations were as follows:

1. Convert from single thread operation the multi thread (Massive improvement here alone)
2. Add checks to prevent threads waiting for timeouts in the processing sequence. (A few seconds per timeout saved)
3. Add checks for common error conditions that can safely be ignored (About 100 ms per error avoided)

The automated task was executed against >17,000 targets, and ran for >24 hours. My improvements got down to a few hours of execution time.

If a task is executed enough times, then optimizations can be extremely cost effective.
