Thread to collect iozone performance tests of the rock64.
When posting a report, please list your board (1G/2G/4G), OS type and version (Xenial/0.2.5), hardware tested (make/model), and the file system it has (ext4/fat32/ntfs/etc). And don't forget to use code tags so the formatting doesn't stuff up 
If you don't have the iozone package installed yet: sudo apt install iozone3
Set the CPU governor to performance (as root, i.e. sudo -i first or pipe through sudo tee):
echo performance >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Mount your drive, change to the mount point, and run the below to run your tests:
iozone -e -I -a -s 100M -r 4k -r 16k -r 512k -r 1024k -r 16384k -i 0 -i 1 -i 2

Hello all,
Sorry if i already missed the posting but I have been trying to change the username in the terminal from somthing other than pine64@pinebook. I have changed my name on login but in the terminal still keep the old username. I also tried using:
Code: usermod -l newname pine64
and i get the message:
Code: usermod: user pine64 is currently used by process 941
The number at the end changes but I get the message everytime I have tried.
Is is possible to make this modification?
Thank you,
Coyote

Maybe to share for others that want to have this installed and find that it is hard to find the right sources for the pine64
influxdb installation
The standard download page does not show the right pine packages
use the following
Code: curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
sudo source /etc/lsb-release
echo "deb https://repos.influxdata.com/${DISTRIB_ID,,} ${DISTRIB_CODENAME} stable" | sudo tee -a /etc/apt/sources.list.d/influxdb.list
After that simply install with
Code: sudo apt-get update
sudo apt-get install influxdb
Grafana Installation
mainly coming from https://github.com/fg2it/grafana-on-raspberry/wiki
To get it working on the pine use the rpi2/rpi3 package.
You can install it by hand accoring to the instructions in the wiki.
If you want to keep it up2date you best use the apt installation.
Code: sudo apt-get install apt-transport-https curl
curl https://bintray.com/user/downloadSubjectPublicKey?username=bintray | sudo apt-key add -
echo "deb [arch=armhf] https://dl.bintray.com/fg2it/deb jessie main" | sudo tee -a /etc/apt/sources.list.d/grafana.list
the key difference here with the standard instructions is:
deb [arch=armhf] https://dl.bintray.com/fg2it/deb jessie main
Once done you can simply install
Code: sudo apt-get update
sudo apt-get install grafana
Hope this helps you

Hi All,
happy new owner of a 14'' Pinebook. So far, everything is going swimmingly. Only bugbear: I am trying to switch from MATE to LXDE. I have successfully installed LXDE via apt-get, but for some reason, the log-in screen won't give me LXDE as a choice of sessions, only MATE. Any ideas how to remedy this?
Otherwise, lovely machine.

I just got the 14" version, a day ago. Had to pay $30+ shipping, then $41 brokers fee. I'm in Canada, a partly communist country I guess. I saw the same laptop on another site selling with "epacket" scam, which never has brokers fee.
Anyway, rather happy overall. There was a bottom screw missing from the laptop. Also, touchpad seemed lifted in the front. One USB (right one) seemed to have some red glue in it, and nothing would fit in it. It seemed broken and glued on.
I opened it up, changed the 16 GB eMMC for a 64 GB eMMC. I saw that the right usb port had a metal piece with glue stuck in that wasn't part of the main board. Was able to remove it with a flathead screwdriver and a bit of skill. Seems to be a piece they use to position the usb port. When removed, now had a nice right usb port that works.
The touchpad has three little plastic "hooks" that hold it on the bottom. The center one was above it's supposed position, and this is why the touchpad wasn't properly seated. I just pushed the plastic and snapped the hook into place, solved that problem.
The 16GB eMMC that came with it had some type of Linux on it. The 64 GB eMMC has Android. I see no way to change the 64 GB eMMC to Linux. I would like to install Debian from USB, but have not figured out how to get into the BIOS or the boot loader.
Can anyone help me on this last part? Open up the boot loader so I can play with the laptop and Debian, FreeBSD, and a few other fun things? I don't have a eMMC flasher, otherwise I would go that way. I don't need much help, just the ability to start.
The laptop is surprisingly a good build, despite the lack of QC. Also, the battery seems like the flexible type that likes to explode, but so far so good.

| Performance Bottlenecks and Swap |

So, I've run into what I consider a concerning amount of CPU hogging due to kswap and running out of physical RAM/loading up the swap in the default Ubuntu MATE install.
2 gigs + 1 gig swap is a bit light to multitask anything in a GUI, especially if one of those tasks is Chromium.
So...
Anyone done anything to mitigate this?
It doesn't appear to be too terribly easy to fix this stuff live, which is not shocking as the default root fs is the one I would need to shrink.
I'm leaning toward grabbing a low-profile USB flash drive and using it as a lower priority swap than the default zram (which seems pretty zippy as it is supposed to be but is too small IMO for many things), but if anyone has a simple or elegant solution, I might try it.
Anyone try to use resize2fs from an SD card? Anyone try that+swap on the eMMC vs a USB drive and compared performance?
