Speedy Google Chrome on Raspbian, use ramdisk

Create directory:

sudo mkdir -p /chromium

Create small RAM disk definition:

echo "tmpfs /chromium tmpfs defaults,size=64M,mode=0777 0 0" | sudo tee -a /etc/fstab

See all content:

sudo cat /etc/fstab

Mount RAM disk:

sudo mount /chromium

Launch browser and create and configure base profile:

chromium-browser --user-data-dir=/chromium/chromium

Exit the browser and create backup:

cd /chromium && tar cf ~/chromium.tar chromium/ && cd

Remove everything to test restore from backup

rm -rf /chromium/chromium

Restore from backup:

tar xf ~/chromium.tar -C /chromium/

Test if everything is working:

chromium-browser --user-data-dir=/chromium/chromium

Modify or create anew startup script '~/.profile' to prepare the tmp profile:
