That's interesting. What do you mean by transmission rate? Are you seeing dropped packets? ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-sparc64 To unsubscribe, send any mail to "[EMAIL PROTECTED]" No, it just doesn't transfer as many as it does without polling. Without polling it transfers like 8MB/s, with polling it does less than this and there is twice the latency. -- Alexandre Vieira - [EMAIL PROTECTED] ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I use device polling(4) patch for hme(4): < http://docs.freebsd.org/cgi/getmsg.cgi?fetch=17147+0+archive/2006/freebsd-sparc64/20060423.freebsd-sparc64 > -- With Best Regards, Andrew Belashov. Hi, Thanks for the tips! I've added the patch for hme polling and I'm recompiling the kernel. I've striped the kernel a lot and I'm compiling with -pipe -O2 -fno-strict-aliasing. AFAIK there isn't any CPUTYPE available for this cpu.

Err... sparc64 is now a tier 1 supported architecture in 5.x: see http://www.freebsd.org/releases/5.1R/hardware-sparc64.html and http://www.freebsd.org/platforms/sparc.html Support is rather better than "rough", although there are apparently some problems installing using the Sun console -- you should use a serial console instead. It's also the case that 5.x is not really suitable for a production system yet: the releases are marked as "New Technology" -- see http://www.freebsd.org/releases/5.1R/early-adopter.html This also makes 5.x rather less suitable for FreeBSD beginners. The soon to be released version 5.2 (due early in December) should be yet another leap in stability and performance. That release might be most appropriate for the OP if he's willing to wait for it.
