But definitelly I was waiting for an extent based FS as we talked about this more than one year and a half ago, when you described me your plans for reiser in an interview on Linux&C. Now, will have to find some time to set up a test, possibly on a 64 bit CPU. bests Luigi On Mon, 5 Jan 2004, Hans Reiser wrote: > Date: Mon, 05 Jan 2004 14:04:58 +0300 > From: Hans Reiser > To: venom@sns.it > Cc: Steve Glines , linux-kernel@vger.kernel.org > Subject: Re: file system technical comparisons > > You can read www.namesys.com for a description of reiser4, and > www.namesys.com/benchmarks.html for some benchmarks. > > There are no well done independent benchmarks unfortunately. > > Of my competitors, and not considering ReiserFS (about which I am not > objective), I would say that if you don't have really large files and > don't have any large directories, ext3 offers the best performance. > > If you have large streaming files, look at XFS.
