BPI-M2+ unusually slow write speeds

[bpim2puser]

Hello, long time Banana Pi user here.

 

I have a BPI-M2+ and recently decided to write Armbian_23.02.2_Bananapim2plus_bullseye_current_5.15.93_minimal.img to emmc. I am using cat6 over gigabit LAN and am seeing scp and rsync transfers to the device averaging 1.7mb/s. Transfering an 850mb file took unusually several minutes. It starts off at 40mb/s then quickly drops to under 2mb/s. Is this typical? I would think over LAN I would be seeing much faster speeds.

 

Untarring this same 850mb archive also took unusually long. Could the emmc be damaged or on it's way out? How would I check?
