Anyone have a Raspberry Pi 2 willing to run a benchmark?

[pqwoerituytrueiwoq]

I am considering upgrading my model B r2 so I'd like to see if the better CPU has any impact on wired network performance
the only online benchmark i found did not test dual link usage so that is why i am asking here
i would like to see the output of iperf -c $IPERF_SERVER_IP -d (the -d is important)
to start the server process run iperf -s you can get the ip address from ifconfig
Please to not test over wifi, Linux box <-> Router/Switch <-> Rpi_b2
it does not matter which is server and client, if it is no better than my old model B pi i can look for a old B+ board which needs less milliamps

I'd test it, but I'm afraid it'll have to wait until my desktop is built.

No idea what you were actually looking for but here you go:

Pi -> Host:

I was wondering if the cpu was bottlenecking the net I/O
thanks CharlesA (http://ubuntuforums.org/member.php?u=923868)

i have my pi acting as a reverse proxy, looks marginally better than i get on my pi, well before i updated the linux 4.1
https://github.com/raspberrypi/linux/issues/1248
happen to know how to revert it?

you running the 3.18 or 4.1 kernel?

Not sure exactly. Do you still have the older kernel installed?

Linux pi 4.1.7-v7+ #817 SMP PREEMPT Sat Sep 19 15:32:00 BST 2015 armv7l GNU/Linux

I've been using this: https://minibianpi.wordpress.com/

If it matters, that box is being used for DNS.

[pqwoerituytrueiwoq]

running 4.1.13+
it was installed via apt-get upgrade, i was not expecting a kernel update out of it, im sure the unattended-upgrades package would not install it since i was still running 3.12 for the past 180 days

i'm still on wheezy, ill upgrade to the b+ i ordered on ebay (http://www.ebay.com/itm/131687047427) (link in case anyone wants a cheap b+)
i have a larger sd card and i want to upgrade some stuff in my diy case, probally a full days worth of work, ill put off the psu upgrade plans till i get a new one, hoping to gut 2 wallorts sand get them in the case

[CharlesA]

Huh. I wonder how you are running a newer kernel than I am.

In any case, it looks like it's a bit complicated to downgrade the kernel. :(

[pqwoerituytrueiwoq]

a very very long time ago i used raspi-update get get a kernel that was not officially stable, cause it fixed a stability issue with the network interface
that reboot was the 1st i ever gave it, all others were a result of power failure, aside from when i changed out the power block

[pqwoerituytrueiwoq]

so how does minibian compare to raspbian jessie lite? only ask cause raspbian jessie lite has a newer release date

No idea, I wasn't even aware they had an official minimal build of Jessie. I'll have to check it out. I do not believe it was there when I was looking for a minimal install of Jessie for my Pi.

I do not believe it was there when I was looking for a minimal install of Jessie for my Pi. and there in lies what i was wondering
