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

Berzerk

Well, around here all the kids were required to buy devices for school. So they could run 'chrome'.

Threw some SSDs in the old laptops, and gave them to the poor kids. Parents didn't have to waste cash on new chromebooks, and they were able to do their school work.

Just a matter of knowing where and when.

A lot of people are using Raspberry Pies, and those are 'older' depending on your perspective.

'Best connectivity'. You can feel the quality!

But it's cardbus and that laptop supports it so it's probably 32bit PCI. You would hope for more than 200Mbps! (or I would at least).

Where are you at - my grandkids all got devices free from the school.. My six year old grandson got a ipad, and 10 year old grand daughter got a dell laptop.

Berzerk

@stephenw10 That is what I thought. But didn't notice it as an issue, until I upgraded with my ISP.

@johnpoz Alberta. School Board ant no piggy bank. They offered devices, but not free. Cheapest were still $300CAD.

stephenw10

Check the PCI bus. Maybe it has something else on there doing something funky? pciconf -lv

The FreeBSD drivers for other things of that age are probably....sub optimal!

Disable anything you can in the BIOS etc.

What does your /var/log/dmesg.boot look like? Errors in there?

johnpoz

That sucks.. But even here in chicago they were giving away devices.. Pretty sure CPS gave away like 100k devices, with priority going to lower income families..

edit: They want them back after this is all over though.

Berzerk

@johnpoz And people say Canada has more free stuff.

johnpoz

I am curious where that budget came from ;) You would hope that the makers would step up and donate, or atleast offer them at fraction of cost, etc.

But a new pi would be a great little device for sure - at very low cost.. problem would be is I don't think they make enough of them for the situation we are in.

@stephenw10 Ya, there are a few things going on, on the bus.

Dude, time to throw stuff away! It's nostalgic and all, but old tech is rarely useful.

Well, if we're talking antiques...

Morse sounder

Several years ago, I salvaged this from a telecommunications office in Geraldton, Ont., which was going to be demolished. It would be from around 1935. 1 Gb is a bit of a stretch for it.

You have no idea. Well, maybe you do.

@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.

Steve

Berzerk

@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.
