multithreaded dll - what is std::_Lockit?

[alan.lemon]

I am working in VS2005 and I am created a multithreaded dll. For this
particular project I need my code to be as fast as possible so I have
been using a profiler to see where any bottle necks exist in my
project. I am using Compuware's community edition profiler and
interestingly a lot of the time that my project spends is in :

std::_Lockit::_Lockit(int)
std::_Lockit::~_Lockit()
RtlEnterCriticalSection
RtlLeaveCriticalSection

I have done some searching around, but I don't understand what these
objects/functions do and if I can do anything about it. Any help would
be greatly appreciated.

It's implementation specific. Ask in an MS newsgroup.
