We have a Sparc-20 running Netatalk 1.3.1 with AFS, disk cache turn on (about
200MB of it), and standard configuration for SunOS 4.1.3_U1. This system runs
only Netatalk. The problem we're seeing is that after about 45-50 user get on,
the repsone time at the MAC's gets really bad. The other traffic on this
ethernet segment is reasonable, so I would think that a Sparc-20 would be able
to handle a lot more users than that...
Looking at vmstat and iostat it seems like the cpu is about 40% idle and we
have plenty of memory (256MB). I/O seems ok and I don't think it's AFS since
the major applications that are being accessed are local copies (i.e.
replicated volumes in AFS). So, I'm wondering if there are any tuning things
etc., that I might try to get better performance out of this box.
Any suggestions? Or, specifically, are there any tuning knobs in Netatalk I
can twist?
