Good article.

You are rather humble as you are actually more than just "a coauthor of U++ framework" Smile

Best regards

Good article.

Thanks. It is actually kind of fun to write these. And it really shows (in the traffic).

I would like to release at least one per month and have about 20 U++ related articles by the end of year.

Those benchmarks are really impressive and hard to beat. Great job!

Not sure that raw performance will help us convert a lot of new people over to U++ in this day and age, but it is good to have.

PS: I'm interested on how the benchmark looks with long strings (512+ characters) in the vector? Especially in the std one. Did they switch their implementation over to move internal elements?

Seriously, std::sort vs Sort with long strings is not as clear win (if I remember well, about 2x).

Anyway, both GCC and MSC now has moving std::string, but it is till much slower than plain nice memcpy... Smile

(I am speaking about e.g. Vector::Insert here).

Oh, BTW, now that you have brought it up: I have totally borrowed the idea of memcpy inside of container implementation from you.

Hope you don't mind Smile

It is open source, after all, is not it... Smile

So, you have started your own framework?
