Well it very much depends HOW you do it. Like the ~= operation in 
ctfe is awfully slow and wastes a lot of memory depending on the 
size of the string, but if you preallocate and copy memory in 
chunks it isn't too bad at all.

And if you use format!"str"() in ctfe that alone can be a real 
speed killer.

That's why I wanna see the code, it is possible there's a fairly 
simple bottleneck to look at.
