Unfortunatly the DiskIO (to SD Card) of the Pine64 is very slow in comparsion to RPI2B (or RPI3). root@rpi2b:~ # dd if=/dev/zero of=/var/zero.img bs=1m count=1024 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 80.823823 secs (13284967 bytes/sec) root@pine64plus:~ # dd if=/dev/zero of=/var/zero.img bs=1m count=1024 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 383.600722 secs (2799113 bytes/sec) Both devices running r327391 with without any debugging, INVARIANTS, etc..
