What is usable latency for ssh and RDP?

-2

What is usable latency for ssh and Windows Remote Desktop Connection (RDP)?

By usable, I mean for things like editing text through a text editor over ssh or RDP so that the latency wouldn't drive the person nuts and/or significantly hamper productivity.

It seems hard to simulate different latency speeds so if anyone could share some experience with a latency that was too much (or ideally a latency that was just bearable), I'd appreciate it.

I live in Europe and have few linux servers in diffrent locations.

Frankfurt:

30-100ms ping, working with SSH is comfortable

Amsterdam:

200-300ms ping - SSH is not very comfortable, but it's possible to work

New York:

500-1000ms ping - forget SSH with latency like this, typing 10 character word takes 5-10 secods

I have no experience with RDP on "far servers", but I guess it would be similar to ssh.

For NY server (500ms+ ping) - I write bash scripts or just commands in notepad on my laptop and paste them into SSH.

Seems strange the ping is 10 times worse from Frankfurt to Amsterdam (about 450 km). It's entirely possible to get 30-100 ms pings to any major city from another. – Louis – 2014-11-14T05:25:06.243

Yea, I was thinking about this. I guess it is my server provider fault. I haven't tried to ping from Frankfurt server to Amsterdam server... – Kamil – 2014-11-14T06:11:46.947

anyway, +1 for the posting the experience at different pings – Louis – 2014-11-14T15:57:28.240

Above 400ms isn't very comfortable; working around in VIm and typing commands is a huge pain, and correcting a typo 20 chars back takes at least 30 seconds.

Yea, typos are painful in slow SSH :) – Kamil – 2014-11-13T19:45:33.123
