Not getting properthroughput on gigabit devices. 200mbps when it should be at least 600mbps

Any further details of cardbus0? cat /var/log/dmesg.boot | grep cardbus0

@JKnott Oh wow. And I thought my MFM HD with a carrying handle was neat.

stephenw10

Could try booting verbose mode:
Add boot_verbose="YES" to /boot/loader.conf.local. Create that file if you don't have one.

Be good to see it report the bus width and speed at some point.

But to be honest even I would probably just move onto something less problematic. Unless it's just a challenge at this point.

@stephenw10 Well like I said, I've got a core 2 quad I can use, and I'll order a Intel PRO/1000 dual port server adapter for it. Then I'll have a third port for testing seperate network if I want.

But it is a challenge. I'll add that to boot, and get back to you.

Its a challenge to start a fire with rubbing 2 sticks together, when you could just use the lighter in your pocket.

I get it if your plane crashed in the mountains, and you need to get the fire going to cook the guy next to you that didn't make it..

Or hey your doing a good thing by getting this old pos laptop working for the poor kids. But for my internet router.. And your 600mbps connection - which I take it isn't freaking free.. Why dick around - just buy something current that you know is going to work and be problem free.

Sure if its your hobby to get old shit working doing shit it was never meant to do.. Then have at it.. But sure wouldn't use it for "my" actual internet connection.. Just Saying..

You hobble together some shit parts from yesteryear, and every time you don't get the speed you think you should be getting that your paying for.. Is it the isp, is it something else - is it my pos 15 year old hardware that my new toaster oven has a faster cpu than ;)

@stephenw10 @johnpoz @Derelict @JKnott

Well, last night I switched to a Dell Core 2 quad with 6gb RAM.
Same Ethernet. 1 Intel/Pro1000 and 1 Realtek8169 (Dlink PCI)

Hooked it up, imported the settings, and I'm getting 600mbps easy now. So it looks like it was the CPU as the main roadblock.

Thanks for all you guy's help.

It was fun.

akuma1x

@Berzerk That looks better!

Ok, one question remains... what interface is that Realtek NIC running - WAN or LAN? I thought you were going to try to get away from that stuff...

Jeff

Berzerk

@akuma1x It is running on the lan side. I'm going to be putting a Dual port Intel/Pro1000 in its place, but It has not arrived yet.

I mean, I only ordered it yesterday, and I wasn't going to pay for overnight shipping. :) Being as how cheap I am.

stephenw10

I'd bet it was the cardbus in the laptop somehow. That mobile core2 CPU is just not that slow.

It would be interesting to try that just using VLANs on the Intel NIC. Only out of curiosity at this point though.

Steve

@stephenw10 Ya, I was thinking that to. HP probably threw that PCMCIA port on there, to say "Hey Look, you can add another port if you want!!" Not expecting anyone to actually use it. After all this was a 'business' laptop, the business that bought it would have forked out the cash for what they needed in the first place, rather than buy a basic model and add peripherals.
It does also have an expresscard port, so maybe that would actually give the speeds properly. (I didn't have any express cards lying around.)

stephenw10

Oh, yeah just use express card then. Almost certainly not restricted in the same way.
