I wouldn't put too much emphasis on that benchmark as the
implementations appear different? Note that Felix compiles
to C++, yet beats C++ in the same test? Yes, Felix claims to
do some high level optimizations, but doesn't that just tell
us that the C++ code tested wasn't optimal?
Languages should be fast by default. I always find it missing
the point when people go crazy during these benchmarking
tests trying to make the code as fast as possible by tweaking
both the code and the compiler flags. Go through that effort
with a 2 million line app. Tell me how long that takes.
YES +1000
I agree with the sentiment, but you often do want to spend time
finding hot paths in your app and optimizing those. In a 2
million line app, there will not be 2 million lines of code in
the hot path. So figuring out how many tricks you can do to get
something going fast does have quite a bit of value, even for
large apps.
First of all, there is not much point optimizing the language for
people who are capable of optimizing everything to the extreme
themselves. D already has as much power as C/C++ for them.
Second, yes, anyone should excercise some basic optimization
attempts before calling a language slow. Yet, not everyone will
come up with the same ways to optimize and some people will
invariably fail. Moreover, the same person may fail, depending on
what he was writing the week before and how much coffee he had.
But even assuming that you optimize some hot paths, there are
going to be the rest of the code that is slow if the language
leads you to slow solutions by default.
More importantly, the slow software is usually a product of
write-it-ASAP mentallity, and of people who are *not* good
programmers. Optimizing their products automatically means that
80% of software that you use everyday (photoshop plugins, office
programs, mobile apps) is going to either run much faster or get
released to the marked sooner, which is a big selling point for
the language.
