Slow ssh


hi all.

i have a strange problem when SSHing into DH from home.
altho my internet speeds are fine,
interacting with the shell is very slow.
sometimes i have to wait 3 or 5 seconds after i type something for it to show up, which is pretty debilitating.

anyone else seen this ?

round-trip (ms) min/avg/max/med = 22/31/73/26

… hmm, is it that 9% packet loss ?
i’m going over a wireless lan, maybe that’s it.

i tried running a wire and didn’t notice any difference,
but i didn’t check the packet loss either so i’ll try that again.


well getting the wireless out of the loop dropped the packet loss to 0%, but i’m still getting some fairly significant delay in shell responsiveness.

sshing in from work, which has a really fat pipe, is very responsive.

so maybe it’s just the inherent delay in DSL.

i’m using fairly fast speakeasy DSL, winXP, putty.


If that latency was caused by your connection, I would expect to see ping times of 3000ms not 20-30ms.


right, the latency is good
but i wondered if high packet loss was the issue.

… which i’ve decided it’s not,
since it’s still quite noticable with 0 or 1% packet-loss and fast pings.

thanks for the reply
