I wrote a small program that generates 400 000 lines of code in several languages to benchmark their compilation speed.

update Turns out generating one function with 400k lines of code is a bad idea :) Go and D segfault, Java simply refuses to compile. I'll modify the test soon.

You can read the code of the generator here.

It's a bit silly, all it does is generate the following pair of statements 200 000 times:

a = 1 
println(a) 

a = 2 
println(a) 
... 

I'm aware that in no way does this represent real code, but it can give a general picture, and all compilers face the same challenge.

Rust and Swift took too long to compile 400k lines, so I tried smaller numbers:
