That would be half of the 1GB :KVA space and large systems really need that space for things like network :buffers and other map regions. : :-DG : :David Greenman :Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org :Creator of high-performance Internet servers - http://www.terasolutions.com What would be an acceptable upper limit? 256MB? 128MB? The test I ran (Kirk's news test) ate around 60MB for the "FFS Node" memory area before the number of vnodes stabilized, on a 1GB machine. I would say that a 128MB upper limit would be too small for a 4G machine. A 256MB limit ought to work for a 4G machine Since most of those news files were small, I think Kirk's news test code is pretty much the worse case scenario as far as vnode allocation goes. -Matt Matthew Dillon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
