| So I was getting lag between the local echo on my screen and my input into the mud.
Similar as to described in this thread: https://www.gammon.com.au/forum/bbshowpost.php?id=9930
Just like the complaints in that thread, I was coming out of zMUD and could notice the lag.
Something about local echo in that thread triggered a thought, and I disabled it.
Delay instantly gone. The client became super responsive, faster than zMUD even.
Colour on local echo didn't make a difference, just that it was enabled.
No spam filter on, no spell check.
Just thought you'd like to know, even though the thread is old. I would have revived it, but that didn't seem to be an option. | Top |

We're down a home page at the moment, sorry.
I definitely think it is more responsive with local echo off. | Top |

| Latest version - 5.06
We're running a heavily modified version of ROM that has been ported to the GO language.
Admittedly there does seem to be a tiny bit of input lag on the mud currently. But we (another mudder and I) observed turning off local echo reduced the lag for us.
Also thank you for your amazingly fast responses. | Top |

What it does is take the time from your last send to the MUD, to the first packet received back, and call that the response time. It also shows an average which you can reset by typing: "reset response time average". |

| After chatting on the MUD we agreed that the issue was really that if you turn on the command echo, the delay between the immediate echo of the command, and the around 0.5 second wait for the MUD to respond, has a psychologically greater impact than if the command isn't echoed. If it is not echoed then you don't get that immediate feedback, and it "seems faster".
Using the response time plugin (above) I couldn't reliably get a slower response with command echo turned on.
What you can do is do commands with command echo turned on, and note the average response time (look in the status bar at the bottom).
Then clear the average (type "reset response time average") and try again, and compare the averages. |
