Raspberry PI 4 performance

  • Hi,

    I'm running a samba server on my Raspberry PI 4 2GB.

    The PI is connected to my workstation and mac via gigabit and has a 250GB Crucial MX500 SSD attached via a USB 3 adapter.

    I just did some performance testing by uploading a 5GB file to the samba share.

    The performance is very good, although it varies quite a lot.

    Sometimes I'm able to max out the interface with around 110MB/s but on the other hand it's often droping to around 70-80mb/s.

    Is there a reason for those drops or some way to get a more stable upload speed?

    Downloading files from the PI is always at 110MB/s
