This can sometimes be solved by using another version of gcc. By the way I
think they work hard on reducing memory consumption. On the other hand I
find code with high template depth a bit suspect.

If you can get near the theoretical maximum of runtime perfomance you are
fast enough in most cases. If you have problems of O(10) in runtime
difference you should really think about what you are doing there.
