This talk was part of the JetBrains .NET Days Online 2022 conference. Details: pages.jetbrains.com/dotnet-da...
Description: F# is a language that stretches across many boundaries (web, backend, domain modeling, etc.) and paradigms (functional, imperative, procedural, object-based) while being simple, succinct, and performant.
But there's more to it! In this session, we'll see why F# is also my favorite imperative, procedural programming language when it comes to performance.
We'll explore why chose F# as the language for our new Discrete-Rate Simulation engine, and how we achieved a 100x speedup over other simulation engines in our industry. All with just F# and .NET.
Speaker: Matthew Crews, Fast F#

I can't imagine seeing something is 10's of millions times too slow and thinking "we can get there"

@WonderfulPlays Год назад

I agree with Khalid, I was rooting alongside the talk! And what a great one it was, Matthew you really have a talent for presenting!

@FastFSharp Год назад

Thank you! That is very kind 😊

@octoplasma2 Год назад

This is the talk I needed! Awesome! Thanks Matt!

@FastFSharp Год назад

My pleasure! Feel free to reach out if you ever have questions.

@daviidon Год назад

Very inciteful, the last "hack" is both awesome and scary.

@FastFSharp Год назад

It is definitely reserved for extreme scenarios 😊

@ARVash Год назад

Awesome talk! I'm really excited about trying to apply these ideas.

@codewithkv 9 месяцев назад

Great talk! I had no idea you could get that kind of performance out of F#.

@10199able Год назад

One of the greatest talks I have ever been

@danielmarbach3235 Год назад

Super geeky but still very approachable! Well done

@FastFSharp Год назад

Thank you! My hope was that it would be approachable.

@HAMYLABS Год назад

Great talk! F# FTW

@mumk 9 месяцев назад

absolutely mindblowing, what a phenomenal journey for that sweet 100x performance improve, you are a great engineer, I am inspired, cheers

@rade6063 Год назад

This is such a great talk

@FastFSharp Год назад

Thank you for the kind words!

@Madison-mk8ce Год назад

love the way you talk about the language. To the point but understandable

Amazing!

@winstonsmith1977 Год назад

Great talk! Why there are so few f# jobs out there? Would love to switch from c#.

@warrenhenning8064 Год назад

AWESOME

Glad you liked it!

Great talk! The chart at 43:59 - could you make this available as log scale? That would make it easier to compare the various changes. The linear y axis misleadingly emphasizes the latest of the fixes, whereas a log y axis may show that other, earlier fixes are more powerful.

Doesn't really help me but here you go: drive.google.com/file/d/1lUEdkz4XqvDnJJXFTCtq5cE0WyvK8mB7/view?usp=drivesdk

@DaveYostCom Год назад

@@FastFSharp Thanks! The linear chart does misleadingly emphasize the latest of the fixes, whereas the log chart clearly shows that the most important fix was the first one, to use mutable. (I would set the lower end of the y axis to 10,000 to make it easier to see the relative benefits of each fix.)

@@DaveYostCom Glad you found it useful 😊

@DaveYostCom Год назад

What happened to the logarithmic plot? Didn’t you post it here?

@ks1970in 6 месяцев назад

just wondering, can it be faster still ?

@nalcij 5 месяцев назад

It runs off dotnet, It’s not blazingly fast but it's not slow either. Think of it like C#.

@L0wPressure Год назад

My man, it's all awesome, and you are doing a great job but i really don't see any benefits in using F# if you go down to such optimizations in the end. Why not use Rust instead?

@zombie_pigdragon 8 месяцев назад

Because, as said in the beginning (1:42), this is a dotnet shop. Training developers in a new language/ecosystem is prohibitively expensive. That said, at this kind of speed, moving the optimized algorithms/data structures to Rust/C++ would be a possible next step for going even faster by enabling the addition of even more micro-optimisations in the hot code, if the speed that the F# reaches was somehow still not fast enough.

@L0wPressure 8 месяцев назад

@@zombie_pigdragon it’s not about the goals of a workshop, but rather the goals of the developer. As far as I remember he wrote it for his work project, not for the workshop, and what I ask is - why this exact language? It’s seems like it was not made for this exact job. That’s all, otherwise great video.

@zombie_pigdragon 8 месяцев назад

@@L0wPressure Sorry, I used "shop" to refer to his place of work. The place that he works uses dotnet exclusively. I do agree though that F# isn't made for hyper-optimized code, but the talk is demonstrating the exact opposite.

@L0wPressure 8 месяцев назад

@@zombie_pigdragon got it, so i misread you initially.
