SSH Slow Connection

Posted December 8, 2021 143 views

When using Putty, commands are randomly quite slow. This doesn’t happen when I’m using the recovery console, and CPU usage is relatively low. I pinged my digital ocean droplet on my local machine and got an average response time of 114ms. useDNS is set to no, and I’ve restarted/rebooted my droplet several times. I was using it just fine this morning, and now it’s acting up for some reason.

Hey there!

It sounds like there may be a network issue between you and your droplet. This typically is the cause for slow speeds in Putty. You can check that by running a MTR from your local machine to the droplet to find out where if any network issues exist. How To Use Traceroute and MTR to Diagnose Network Issues

You can also try using another network to see if you are seeing those same issues.

Hope it helps!

In this guide, we will discuss how to use traceroute and mtr to diagnose network issues. These tools and utilities will provide a good overview of what stage of the network is causing problems. You can tell if an issue falls within your realm of influence or whether you need to contact the owners or maintainers of alternate networks.
  • Thank you! Screenshot This definitely seems to be the source of the problem, but what do I do with the information I’m getting from traceroute/mtr? How do I configure my network differently, or use another network as you said?

Hi @Krakenmeister,

Are you still experiencing the issues? I don’t see any network issues with Droplets so I can only assume it was related(possibly) to your ISP but I might be wrong?

I’m asking as it might have been due to some temporal issues which have been resolved?

  • Yeah, my SSH connection seems to have cleared up just fine. When I run MTR I still get an unresolved host, but for some reason its 100% packet loss doesn’t count towards the total anymore. I tried contacting my ISP and didn’t get anyone that had any idea what I was talking about, but at least the SSH isn’t slow anymore. I just have to hope it doesn’t happen again, but I’ll resolve the question for now. Thanks!
