It can do even better if it doesn't use reflection. I have an unfinished prototype here: https://github.com/KirillOsenkov/MEFMetadata that shows 2x-3x speedup.

@kzu: we switched away from .NET MEF for two big reasons: performance and interop with "nuget MEF / MEFv2".

I used to wonder what was the point of VSMEF not being just "plain MEF", you know, the one that ships with .NET? Well, of course MEF relies mostly on reflection (for the attribute-based model, as well as the conventions one), meaning all assemblies and types will be loaded at container-init time. But how bad can it be, right?
So I got curious, run a LINQPAD query (shown above) and got a whooping 196 assemblies exposed as MEF components via VSIX extensions built-in VS2015. So, bottom-line:
