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]"

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.

Netra T1 105 (sparc64) optimization
Hi, I'm responsible for building a testbed for a network service solution and I was given some old hardware to work with. For example, I have a netra T1 105 working as a bridge between two vlans in order to use ipfw+dummynet to create packet loss and latency tests in a platform that was already deployed (quick and dirty solution). At the moment I configured the machine to do the job and made some benchmarks but haven't yet optimized anything so I can benchmark it later on to see the optimizations effect. This is the first time Im working with a sparc64 box with freebsd and I would like to know what improvements can be done in terms of specific sparc64 optimizations (ex. gcc flags/cputype), kernel/tunables recommendations, comments onthis specific job (bridging and messing with the packets in layer 3) or any other usefull info. You can find the base configuration of the machine here: http://nullpt.googlepages.com/netra.txt Thanks in advance for your time!

Netra T1 105
Hi lists, I got my hands in some Netras T1 105 and I'll be installing freebsd over the network since I don't have CD-ROM drives. I was googling around to find a recent kernel/loader to use in the net installation but I couldn't find anything. Anyone knows where can I find these? PS: In a last resort I think I can compile a sparc64 kernel in another non-sparc64 machine. But what about the loader? TIA.

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.
