That's also my experience. Using C++ in a fairly high level
projects involving interfacing to servers/cloud or any business
application C++ is just a no go, at least for me. C++ has almost
nothing out of the box, right now C++ doesn't even have its own
socket library. Then you have search of 3rd party libraries which
takes time and you really have to watch out when it comes to
licenses which reduces the amount you can choose from. 3rd party
libraries also varies a lot when it comes to quality. You have
Boost which is quite good but when you include it will increase
the compile times by a crazy amount.
Anything not low level, stay away from C++.
Java is better with good library support but suffers from high
memory consumption. You cannot chuck several Java processes in a
Linux system with only 512 - 1 GB of RAM because you will run out
of memory very quickly. 1 - 4 java processes but then you're out.
D fills the spot between Java and C++. You can quickly code
something in a working condition than C++ which is also more
stable. Memory consumption wise I expect it also to be between
C++ and Java. I would like to see a plug in referenced counted GC
because that would decrease the memory consumption as well which
is good for those small but many services you often see in
