SSHFS/SCP and me

[Arokan]

Hey LT-Techies!

 

I'm looking for possible issues with file transfer over SSH.
I have a raspi4 (twisterOS -> 2x3TB HDD via USB3-2bay hub, in one logical volume) as NAS/Cloud and PC (debian bullseye), laptop (win10 over sshfs/winscp) and phone as clients over sshfs.
A few days ago, I noticed the speed being slow.. by which I mean stable 850 kb/s.
I tested drive-to-drive-transfer within devices, no problems. Anything that uses the network, however, is dead-slow.

NAS-PC, PC-Phone, NAS-Phone, aaaall dead-slow.

Router is showing full 1Gbit/s and internet-speed is not impaired.

SCP is exactly as slow. I tested this because from google-research "SSHFS slow but scp fast" is a common result.

 

Soo... I have no damn idea what could've gone wrong!
To my knowledge, I changed nothing relevant during this period. No installations or updates (looked up the apt-log).
 

So, I'm desperate enough to post my problem here. I'm grateful for any ideas.
Let your inner Sherlock figure this out!

My fstab is:

pi@192.168.13.3:/path/to/folder/                   /path/to/folder        fuse.sshfs      delay_connect,IdentityFile=/home/$USER/.ssh/id_rsa,idmap=user,port=$PORT,rw,uid=1000,gid=1000,nosuid,nodev,_netdev,allow_other,default_permissions,reconnect 0 0

T.i.a.: Arokan

Update1: No high CPU-Usage on either device.

how is the pi connected to the network?

sshfs is not slow, at least nowhere near this slow. the most likely culprit is the network connection on your pi.

Okay, it's now 16 hours later, and Linus has been right all along: As soon as you post your problem on the internet or hire a professional, it doesn't take long until you fix it yourself.
Now: It couldn't be the pi, because when I draw something from my pc to my phone, it was slow as well.

So what did I do? I restarted my router... figured since all Network devices are impaired, it must have something to do with it.
I'm now back to full 30MB/s. Still wondering why, because with HDD+pi+wired it should be more, but that's a number I can live with rather than .9MB/s

Thanks for your thoughts!
