[Boost-users] boost::thread_specific_ptr performance?

Hi!

What performance characteristics can be expected from a
thread_specific_ptr on various platforms, as compared to other
synchronizing primitives? Does accessing it cost the equivalent of
locking a mutex, or is it generally faster than that?

Specifically, would the cost of accessing it be noticeable if one were
to use it (naively) to manage detailed per-thread logging, generating
many thousands of access calls per second or more.

Thanks in advance!

Best regards,
