It is not really a bug: only the newer Windows (Vista+) have efficient polling. With previous versions, small pollsets have to be used because (apparently) it can only poll over 64 sockets at a time. If the size is over 1000, there is a big performance impact. It is supposed to be handled well in APR (using the new APIs if available). Source: Mladen some time ago. Hopefully, I understood everything correctly ;) Rémy --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
