Faster[1] than Java (glacial, albeit with warmer weather recently) or C (continental drift), slower than Swift, PHP (which truly has become a "kitchen sink" language equal to C++'s reputation for the same) or Python, about the same as Javascript.[2]

[1] By which I mean the languages themselves and minimally-conforming standard libraries rather than ecosystems or quasi-standard libraries like J2SE (Java), Cocoa (Swift) or the browser DOM (Javascript). C++ has a fairly slow-moving (but mature) ecosystem and its "quasi-standard" libraries (Boost, common compiler extensions, Windows and POSIX APIs) aren't as tightly-coupled to the language as the previous three examples.

[2] Both hindered by standards-body bureaucracy and the need to keep backwards compatibility with mistakes, but both popular enough that bigcorps are incentivized to keep things moving along; Javascript is more popular but that's offset by C++'s more efficient de facto process for standards-tracking library improvements (get them into Boost first).

Javascript actually probably moves a bit faster but Internet Explorer compatibility (still likely to be relevant for another 5 years or so) is an even bigger drag on adopting bleeding-edge features than waiting for (your company adopting) new Visual Studio/CentOS GCC/[Some embedded architecture] GCC versions is for C++.
