It is not assertions that make unoptimized C++ really slow, it is the lack of inlining which is critical to clean up template abstraction goop.
It depends on the assertions. In the case of the JS engine, the particular assertions under discussion change the algorithmic complexity of many algorithms, which makes them much slower in practice.
In particular, the "release+asserts" configuration (--enable-debug --enable-optimize) is much slower than the same thing without --enable-debug in the case of SpiderMonkey.
