Date: Fri, 19 Aug 2011 18:28:45 +0900 From: "Jun.Kondo" <jun.kondo@...-g.co.jp> To: David Miller <davem@...emloft.net> Cc: linux-kernel@...r.kernel.org, omega-g1@...-g.co.jp, notsuki@...hat.com, motokazu.kozaki@...com, htaira@...hat.com, netdev@...r.kernel.org, tomohiko.takahashi@...-g.co.jp, kotaro.sakai@...-g.co.jp, ken.sugawara@...-g.co.jp Subject: Re: [omega-g1:10937] Re: [PATCH] net: configurable sysctl parameter "net.core.tcp_lowat" for sk_stream_min_wspace() You suggested to use non-blocking writes, but we think we have to rewrite the Apache code if doing so. That is, we have to make a modification to Apache that depends on the architecture. By using this patch, it can be handled by changing the configuration a little bit on the kernel side for such applications that it is difficult to do so on application side.
