GL-X3000 slow micro SD card transfer speeds

Is anyone else finding slow transfer speeds off the sd card over the local network? On the original fw I was able to transfer a 2GB file in less than 60 seconds, now we’re averaging 10mins. Have tried different devices and different cards (current card is a very quick sandisk SDSQXAV-1T00-GN6MA).

I also noticed this on a usb 2.0/m.2 SSD.

*Edit, after a reboot I was able to see speeds of 17mpbs but seems to dwindle down as uptime increases.
