> string manipulation

That benchmark performs string manipulations that rarely occur in web apps. Web apps need: concatenation, substring, find/replace, maybe with regexps. All of those are implemented in C.

> memory allocation

Web apps don't tend to implement entire trees in pure Ruby. That benchmark is completely non-representative of real-world performance.

What exactly are you getting at? Of course it's easy to find a bunch of synthetic benchmarks that show weaknesses in particular cases. Still doesn't prove anything.

join and gsub?

Nor do other apps but that is what Hans Boehm came up with as a simple GC benchmark.

You don't seem to know what is shown on the benchmarks game website.

Doesn't your regex-dna benchmark kind of prove my point? Just look at the comparisons here: http://benchmarksgame.alioth.debian.org/u64q/performance.php...

C GCC: 2.46 sec

Java: 8.23 sec

Ruby #8: 9.35 sec

It's only about 4x slower than pure C in this case, and only a little slower than Java which has a very good JIT.

How funny of you to say that while acting as if the benchmarks "prove" Ruby is the ultimate spawn of the devil that eats away any and all performance. The website itself tells you not to jump to conclusions and that the app itself is the ultimate benchmark: http://benchmarksgame.alioth.debian.org/dont-jump-to-conclus...

7 days ago, you could have used the data shown on the benchmarks game website to try and make your point to joslin01.

Instead you chose to dismiss the data.

>> acting as if <<

You seem to have confused me with joslin01.
