Your database was designed for a 7ms disk seek that hasn't existed in your rack in years.

You're just carrying that debt now.

foldb starts from the log. State is fold(log). One isolation level: strict serializable.

Fresh #gRPC benchmarks just dropped (Apr 2026) and the results are 🌶️

# 1 CPU: #Rust Tonic dominates at 102K req/s using just 15 MiB RAM

# 2-4 CPUs: #Java Vert.x takes the crown at 153K req/s... but needs 305 MiB to do it

Meanwhile Rust Thruster does 139K req/s on 12 MiB. That's 25x less memory than Java.

#dotNET quietly sitting at #4-#8 across all configs. No hype, just solid numbers. The boring enterprise choice... that keeps winning.

Scala Pekko & Akka? Surprise top-5 finishers at 3-4 CPUs. JVM tuning is real.

Now let's talk about the bottom of the chart:

- #Python: 4,492 req/s (1 CPU)
- #Node: 12,471 req/s (1 CPU)

That's 23x slower than Rust.

Node doesn't even scale past 1 CPU — 16K req/s whether you give it 1 or 4 cores 💀

But sure, "developer productivity" even when it is AI generating code these days... 🫠

I am excited to share that #NBomber is being used in white papers on distributed systems. This is already the second white paper to use NBomber in its research.

All kudos go to the paper’s author, Preethi Viswanathan.

@kozlovski @kozlovski sorry to ask but what the point to attach a flag of state which aggressively killing people in Ukraine? And please don't say you are out of politics.

Hey #fsharp community!

Has anyone discussed the possibility of organizing an offline F# conference?

I realize we have @amplifyfsharp, but it would be great to meet in person as well.

@tomasgrosup !and
use! _ = new Disposable()
ValueOption for optional args
auto property

[🇺🇦 Anton Moldovan @AntyaDev]

F# 10 seems to be going in the right direction.

I really like the focus on clean syntax like Task.WhenAll replaced by !and

Also, expansion of ValueOption support, and very practical auto property accessors.

Thank you F# team! You are rocks!

[Tomáš Grošup @tomasgrosup]

What is new in F# 10 ?

A new docs page was published (a separate blog post will come out later as well, including much deserved community celebrations!)

Which feature are you going to try out first?

#fsharp question: what is the standard way for handling TaskResult.bindError

https://t.co/0D5nOcX4XF

[🇺🇦 Anton Moldovan @AntyaDev]

C# dev - but F# doesn’t provide built-in comparison operators for Nullable<T> (>, >=, <, <=)

F# dev - this isn’t a big deal.

Hi @ONETUG @AndyLech42,

If you’re looking for new topics or speakers for upcoming meetups, I’d be happy to contribute a session on Load Testing with C# and NBomber.

I plan to visit Orlando in November.
