F# has a programming model for async that blows C# right out of the water. See e.g.
Thanks Brian Ill check that out.
I actually have a pretty good implementation in C# using the AsyncEventArgs model that Microsoft introduced with .Net 3.0 it would be interesting to see what can be done in F#...
Wow, I guess you are talking about
? I used to work on the WCF team, and I had never heard of that until now. Sounds like it's about as close to the metal as you can get in managed code. I am unclear that that kind of memory performance matters (I would guess that other factors will dominate today), but interesting, I had no clue that stuff existed.
I came across the extra functionality when .Net 2.0 sp1 came out, I noticed much better performance when using it compared to the old IAsync method, I think its easier to follow to when you look back on the code a few months later.
Ill have to get a little bit more up to speed on F# then see if I can get a similar version built. The benefits are mainly due to the fact that there are no longer objects created for each send and receive. Once you have a high throughput server you would defiantly feel the benefits. I suppose it goes slightly against the Functional programming mantra in that the buffer part of the SocketAsyncEventArgs is mutable to allow buffer reassignment to a contiguous block of memory to further increase the performance...

has anyone implemented high performance SocketAsync type operations using F#, is this an area the that F# would shine? Or would it be better to stick with a C# implementation?
