Re: [Boost-users] Thread creation overhead & efficiency

Hi James -

My impression was that creating new threads on Windows can be quite
expensive, but I don't have a lot of experience there.  Creating threads in
Linux using posix_threads (also via boost) seems to be quite fast.

However, I have noticed that thread_groups are much slower (factor of 4)
than using my own vector<boost::thread*> and joining each individually.
This is probably because I have only one controlling thread for my vector,
so I don't need mutex.
