Some additional information.
I'm using a binary formatter not a soap/xml formatter so array
optimization should be possible.
Thinking this I tried to use a single dim array like
"short [] x = new short[512*512]"
and that gives very good results.
Something about 4,5 ms per array, but a short[,] is incredible slow (235
ms).
Is this just poorly optimized (will it be fixed?) or is there a good
reason for this significant slow down?
Regards
Axel

Hmm - do you mean that serializing this
[Serializable]
class MyImage
{
public short[,] x= new short[512,512];
}
results in serializing 256K shorts piece by piece?
No array optimizations here?
Looking at the SerializationInfo I can't find explicit array support
either.
Well I simply cant't believe - if that's really the case then I'm
(badly) impressed.

I am impressed that it is marshaling it in 250ms. You have up to 1/4
million shorts. I might make it faster if I wrote the SerializationInfo
prepended with the length of each of these dimensions and only marshal
what's required. But that is just the first idea off the top of my
head.
Thanks,
