Benchmarking guidelines for NAS/Samba
Hi everyone. Just recently installed obsd 4.9 and setup samba to run on it for use at home. I am getting currently transfer rates of 8,9 MB/second on a 100 Mbit connection. I would like maybe in the future to upgrade it into a better machine with a Gb connection, maybe throw it in some RAID controller into it, but first I am interesting in learning on how to benchmark it and figure where the bottlenecks are on the current machine. The current machine contains a VIA C3 1GHz processor, 512 MB RAM, 100 Mbit Ethernet and a SATA HDD. (old mini-itx form factor board I had at home unnused) Can anyone give me some directions, point me to the right tools to use, etc ? Regards, Henrique

To clarify, with vga repost disabled, everything else including wireless
(wpi) resumes just fine. As I don't use text consoles or ethernet very
often I suspend and resume a lot and have no issues.
I have a diff somewhere that adds a machdep.vgarepost sysctl, I should
dig it out after tree unlock to see if it's of any interest.

I use amd64 in everything that supports it, without a single problem related with the architecture itself.

Panic on OpenBSD 5.0 -current 6 Aug 2011 GENERIC.MP
Hello,
This panic occurs when one of our border router with BGP is panicking, and
when the traffic (and bgp routes) failover to this router, it panics. The
router kernel and userland are sync from source repository, build from
source last night.
I haven't had the opportunity to follow the source code debugging
procedure. These are the data which I able to pull by taking pictures of
the panic.

In addition, that box happily can do up to 200k packets/sec as well. I think a PE2850 with 4G of RAM for a firewall is overkill for 25 Megabits/s. Tom Tom
hibernation with APM
Hello all, does anybody please know if there is a way to initiate hibernation on APM equipped laptops that support it *from software*? Thanks for answers. Regards, David

You see that ddb{1}> prompt that I'm quoting from *your* original
email? That's the prompt of the built-in kernel debugger. It even
has a manpage: try "man ddb" on a running system. That's the prompt
you get when the kernel panics or faults; it's completely unrelated to
the normal shell command-line that you would normally get. There, in
ddb, right after you fire up kqemu and get a fault, *that's* where you
should enter the *ddb* commands "trace" and "ps" and "show registers".

Re: hibernation with APM
run apmd at startup then type apm -z to initiate it. Works like a charm on most laptops of quality.

Re: hibernation with APM
Hi Marco. Thanks, but I'm not asking about suspend. apmd -z starts suspend, at least with my Thinkpad and Compaq, both with Phoenix APM BIOSes. Hibernation is sometimes called "save to disk" suspend, while suspend is then called "save to RAM" suspend.
