Speaking *generally*:

I can write an ISAPI filter in C++ that is more performant than a C#
module implementing the same functionality. This would be because the
filter is written in C++.

Also speaking generally:

The C++ version would take 4x as long, would have 4x the number of
bugs, and have 4x the number of security holes. Just memory management
alone in a non-trivial ISAPI filer required very careful attention to
detail.

A handler written in managed code is the answer to an ISAPI dll. There
are so many benefits to managed code I'd never consider doing it in
C++ again.
