So your previous > post has been idiotic blathering. Actually, who's the clueless one here? What do you think FreeBSD runs on? PCs. I don't know what you call a "workstation" here, but FreeBSD runs on the exact same hardware Linux runs on. It doesn't run on SPARCstations or ALPHAs or anything BUT the PC, so it would have been impossible for the poster to run FreeBSD on "a workstation" as you seem to be defining it. If you're going to hurl such charges around, you should first make sure you're not guilty of the exact same ignorance of your subject or you only look twice as foolish as the man you're attacking. As far as NFS benchmarks are concerned, there have been a number of independant tests run against both operating systems (and if you're interested in actually finding out about such tests, you need to go to conferences like USENIX rather than simply speculating that there is no hard data available). Running on the same hardware, NFS performance will generally be greater on ANY operating system which implements its NFS services in the kernel rather than in usermode. That's just one of life's little trade-offs and Linux appears, for now, to have chosen the usermode implmementation. Perhaps there are efforts now underway to change this and, if so, great. I'd welcome another university or research institute sponsored round of benchmarking as I'm sure the goalposts have moved substantially on both sides since folks like Mary Baker's group at Stanford ran its last set of comparative benchmarks. -- - Jordan Hubbard President, FreeBSD Project
