Date: 8 Mar 1994 13:41:15 GMT Organization: Ecole Nationale Superieure de Techniques Avancees, Paris Lines: 14 Distribution: world Message-ID: <2lhv9r$pbt@homea.ensta.fr> NNTP-Posting-Host: bsdtest.ensta.fr Hi, We have made some comparaisons between NetBSD 0.9 and Linux, and it appears that Linux's disk i/o calls are much faster in some case (time gives 4 seconds versus 4 minutes for a programs which make direct acces writing and reading on a file, on exactly the same hardware). It seems that Linux bufferize the file, as NetBSD always write it on the hard disk. Am i wrong ? Is there any way to change this ? -- Manuel Bouyer, Ecole Nationale Superieure de Techniques Avancees, Paris email: bouyer@ensta.fr --
