Hello Andi,
the speed depends indeed on the SD card used. The SD cards used today on netPI is of type Xmore industrial SD card with part number SDU008GXASMM-001E. This card is using a flash controller that is now about 3-4 years old. Flash controller of today's SD cards on the market are much faster. Also I heard that meanwhile there are faster cards available from Xmore as well. (So it is not a slow network connected as you initially assumed).
Fact is that the Raspberry's SD card interface is a well-known bottle neck. So changing an SD card can speed up Raspberries/netPIs processing time tremendously. Also we have recognized this bottle neck and will be switching to SANDISK 8GB industrial SD card with part number SDSDQAF3-008G-I in the next production batch of netPI. We have finished all our tests with this card and can confirm it works as good as the Xmore type but a lot faster.
So back to the timing issue you have detected I can just recommend not to buy a standard netPI we offer on Amazon.de or Hilscher Web Shop, but a netPI in the Revision #2 from Hilscher directly. This Revision #2 netPI does not have a sealed SD card anymore. So you can replace it with your own SD card. You will see then that netPI will be performing as good as your Raspberry (3B).
Thx
Armin
