All of a sudden SSH is really lagging/slow.

@strawberry-3.141 That’s what I’m doing right now… :)

@Mar
Thanks for the feedback. I will change my post and remove the =, so others won’t run into the same mistake.

@strawberry-3.141 My cpu usage (using top) after the pi has booted up stays around 3-5% (using the top command raises this a bit). And memory usage doesnt seem out of control either.

@strawberry-3-141 Hmm… It does not seam to be any module doing it… I’m thinking it’s a “core-dump”, I noticed when restarting that it took a long time before it actually restarted. I’m guessing something did not close down properly, then the memory (or something) is dumped down to a file… Now it’s not happening any longer… Reboots normally. Only thing is that I lost my pm2 autostart of the mirror for some reason (had to do a pm2 startup and run the “setup” command sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u pi --hp /home/pi again… And now it starts normally again… No core file after reboots, all modules back again… Darn! :)

@Mar does the ssh speedup when you shut down the mirror?

Mar

@strawberry-3.141 Oh wow! Ran a pm2 stop mm and the ssh went back to exactly how it used to be. No lag at all and can use nano on the config file with zero lag (could even mouse wheel scroll perfectly).

Then starting MM back up (pm2 start mm) it seems to maintain the quick ssh speed. Upon a full reboot though it seems to get back to being slightly slower.

Just got myself a “core”-file again in the MM root. :) I’m now sure it’s because Electron is crashing. So, it’s probably a memory dump. Still don’t really know why Electron is crashing. It’s not crashing all the time. Just sometimes. But then, I do have lot’s of modules going… :)
