Of course 64 bit kernel can help me overcome the 900M barrier. However, if I can't find the reason why so much memory getting 'lost', it will be difficult to support more heavy loadded concurrent TCP connections. > 2006/11/6, Arjan van de Ven : > > On Mon, 2006-11-06 at 14:07 +0800, Zhao Xiaoming wrote: > > > Dears, > > > I'm running a linux box with kernel version 2.6.16.
