title: ACE vs Boost vs Poco vs wxWidgets
body: <p>I have a considerable amount of experience with <a href="http://www.cs.wustl.edu/~schmidt/ACE.html" rel="noreferrer">ACE</a>, <a href="http://www.boost.org/" rel="noreferrer">Boost</a> and <a href="http://www.wxwidgets.org/" rel="noreferrer">wxWidgets</a>.  I have recently found the <a href="http://pocoproject.org/" rel="noreferrer">POCO</a> libraries.  Does anyone have any experience with them and how they compare to ACE, Boost and wxWidgets with regard to performance and reliability?</p>
  
  <p>I am particularly interested in replacing ACE with POCO.  I have been unable to get ACE to compile with VS2008 with an x64 target.  I mostly use ACE_Task so I think I can replace those with Poco's threads and message queues.</p>
  
  <p>Some other portions of POCO that interest me are the HTTPServer, HTTPClient, and LayeredConfiguration.  Those libraries are similiar to libraries in Boost and wxWidgets but I try to limit my use of wxWidgets to GUI components and the comparable Boost libraries are... difficult.</p>
  
  <p>I'm interested in any experience anyone can share about POCO, good or bad.</p>
