Why, for instance, does the CLR GC not have something like TLABs? The result is that it seems like .NET devs have to worry a lot more about the expense of small, short-lived allocations, while in Java these things are much cheaper.
Overall, I think it's easier to program idiomatically in Java and get decent performance out-of-the-box, while C# may provide more opportunities for optimization without having to rely on something equivalent to sun.misc.Unsafe and offheap allocations.
I've always heard this, but does it actually manifest in noticeably worse performance than the JVM? Go has a much simpler GC, but it's not terribly slower than Java (I do know they are optimized for different things).
It seems like C# is within bounds of Java while also having great performance escape hatches.
Blazor's architectural model makes it impossible to be "performant." It's not even debatable.
What you gain in DevEx you lose substantially in user experience.
Well, it sounds like you have an axe to grind, but I didn’t ask to “prove” anything; I was curious to learn what was meant by the bad-performance claim. I don’t program in any of these technologies; I don’t have a horse in this race.
Let’s try this again:
