When the ACE-library is not an option: e.g. due to a large footprint (even without debugging info, optimized by size, and after cutting by so-reduce tool all unnecessaries it may reach up to 500 K) , it could be an interesting framework to consider. </pre> </blockquote> <pre wrap=""> Thanks for your kindness. I don't like to use ACE too. ACE is too large, too complex. So i decide to develop a lightweight Half-Sync/Half-Async framework. Best regards, stephen </pre> </blockquote> I wonder why was the design decision to use Half-Sync/Half-Async pattern but not the Leaders/Followers pattern which may be more efficient and scalable? (<a class="moz-txt-link-freetext" href="http://www.cs.wustl.edu/~schmidt/">http://www.cs.wustl.edu/~schmidt/</a>PDF/lf.pdf) Does libevent allows implementation of this multi-threaded pattern? </body> </html>
