If you have many records of the same type, I presume that some PreComputeRecordYadda method here
would help, yes?
Yay! That looks like I was looking for. If I memoize the result of the PreComputeYadda, that should help. I'll try it and report how it goes!

I have been using FSharpValue.GetRecordFields to have generic functions that can dynamically dump a seq of records into a CSV file and the like. This is very convenient; however, it is extremely slow. There must be some faster way to achieve that sort of reflection. Does anyone have experience with this problem?
One solution that seem promising to me: If the Reflection interface itself is that slow (i.e., if it's not
merely an implementation issue of the F# library), one could have a
method dynamically generate IL to translate a Record into a Dictionary
and back, and then memoize that method.
