I'm a Linux enthusiastm but a lot depends upon the network
interface; If you are using Token Ring, well, check for
newer drivers. If on EtherNet, well, that comment was
worth less than you paid for it... :-)
I've had good luck using NFS on Linux on EtherNet, but
I've never had enough of a system hammering it. As it
is, having an AIX system access files on a PC doesn't
strike me as that wonderful an idea. The AIX box should
have that kind of job- it has LVM+JFS, which is a heck of
a lot easier to manage (and, after a class on AIX performance
manglement, to tune). Besides, even with a major clock rate
on a Pentium II, the PC architecture itself is working
OK, so you're using a linux box to deliver files since you
need more disk space and you don't want to buy/upgrade
drives from IBM. Right?
Have you checked to see that you're actually tuned for
NFS operations? (biod/nfsdcounts, etc) Your Linux
server may need more nfsd daemons to run to make an
effort to keep up w/ the RS/6000 (I hope you've tuned
the Linux box in other areas, like dropping various
daemons...). As I said before, though, you really need
to be running ethernet or a newer T/R driver...
BTW, the performance class is Q1128; I just finished it
today. Cool stuff. It's also good for folks who do
applications, too, though you still need some systems
