Hi James -<br><br>My impression was that creating new threads on Windows can be quite expensive, but I don&#39;t have a lot of experience there.&nbsp; Creating threads in Linux using posix_threads (also via boost) seems to be quite fast.<br>
<br>However, I have noticed that thread_groups are much slower (factor of 4) than using my own vector&lt;boost::thread*&gt; and joining each individually.&nbsp; This is probably because I have only one controlling thread for my vector, so I don&#39;t need mutex.<br>

<br></div>I was looking into that, but was wondering if anyone had experience to<br>suggest that creation/destruction of threads was a significant overhead<br>before I implement pools.<br><font color="#888888"><br>James<br>
