X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 07 Jun 2007 09:10:33 -0000 Hello Guys, Almost all cases polling(4) adds additional latency. There are some cases that polling(4) helps a little but most cases it wouldn't. So why not remove it or switch to adaptive polling as em(4) instead of resorting to polling? -- Regards, -Abdullah Ibn Hamad Al-Marri Arab Portal http://www.WeArab.Net/
