Well, I did some benchmark tests using the
fio tool, 4GB workload file, sequential reads and writes,
ext4 file system, all defaults values, kernel 4.9.113-50-osmc:
||read bandwidth [MiB/s]
||write bandwidth [MiB/s]
|Vero4k+ internal memory
|Vero4k+ USB port, external SSD
|Vero4k+ SD card reader, SD card A2 + v30
|Vero4k+ NAS, nfs 4, Synology DS214se, Raid 1
So, the external SSD and the A2+v30 SD-card (card read/write bandwidth on my Win10 desktop 67/85 MiB/s) are much faster than the Vero’s hw interfaces + OSMC stack, which means that these table values are at a very rough estimation the max. throughputs with the current kernel + ext4 which can be achieved with the hw platform.
The Synology NAS device is an old and tiny one but still gets DSM updates. Regarding reads it’s capable to get the max. out of 1 Gigabit ethernet even with mechanical SATA disks inside but for writes you can see that the small Marvell Armada 370 CPU inside the NAS and underlying hw is running on the edge of max performance.
