I’ve set up some monitoring over my node. In particular I plot the number of uploaded and downloaded pieces per minute and the amount of data written and read from my physical disk. I see that the amount written more or less correlates with the number of uploaded pieces.
I observe solid 20 pieces/minute downloaded which should translate to 40+MB data read per minute. However the amount of read data is next to zero which makes me think that either most of the data sits in the OS cache (my RPi 4 has 4GB of RAM) or that the read request is for an incomplete piece (no idea if this is a thing).
If it’s just a test traffic then I feel it’s not testing the node close enough to what would be a production traffic (I’m sure it’ll read cold data almost always).
