digitalmars.D - Benchmarking build times

Hey I want to benchmark speed of D and other languages. I think
I'll use rosetta code. It has functional equivalent code in
several langs.

What is a large program on rosetta? I will copy that program many
times and modify each with sed so the names are abit different.
Then write a makefile and build.

I answered this post, but I can't see my post. If you compile a 
long D C-like program you have a smaller compile time compared to 
compiling a shorter D program that uses std.algorithm and 
std.range a lot, because of all the templates that need to be 
compiled.

I found https://github.com/acmeism/RosettaCodeData. Is it fresh?

To estimate build times I'll concatenate all files into one.
About 6K LOC. Then I'll duplicate that file. Sound good?

The most recently update is 5 months ago, but most entries are 
one year old. So they are not updated. I update the site 
frequently (perhaps I updated 200-300 entries for 2.066).

Some entries are infinite loops, some load external libraries, 
some can't even compile, some entries use lot of memory to 
compile, and so on. You will have to comb every program. And most 
programs contain templates, so if you don't add their main 
function, nothing gets compiled.
