Earlier today i made myself a lightweight memory stream, which basically writes to a byte array. I thought i’d benchmark the two of them to see if there’s any difference – And there was:
(writing 1 byte to the array)
MemoryStream: 1.0001ms
mine: 3.0004ms
Everyone tells me that MemoryStream basically provides a byte array and a bunch of methods to work with it.
My question: Does the default C# library have a slightly better performance than the code we write? (maybe it runs in release rather than debug?)
The .NET implementation was probably a bit better than your own, but also, how did you benchmark? A couple of million iterations, or just a few? Remember that you need to use a large test base so that you can eliminate some data (CPU being called away for a moment, etc) that will give false results.
