What is a good ping time on FTTC?

Just got FTTC, and my ping times seem to be going between around 23ms up to 65/70ms.

I've got a TBB remote ping test running as well, and that also reports the odd big spike, to over 100ms.

What ping times should I be expecting?

Thanks.

It depends on a number of things like...
how close the server you are?, if you pick the same server every time?, do you have interleaving on the line?

If I ping www.bbc.co.uk then I tend to average around 16, if I ping elsewhere though it can be a lot higher than that.

Over 100ms if no one is using the net to do something seems high (unless you're pinging a server in another country), although you will tend to get the odd spike every now and again, as long as you're not getting it all the time it's not an issue.

what's your ping when you ping www.bbc.co.uk via a command prompt ??

I'm getting 5ms pinging www.bbc.co.uk;

This is on a Zen 80/20 connection with Zen backhaul and is the best of the FTTC connections I manage. You can see the current 24hr TBB ping monitor snapshot at http://www.thinkbroadband.com/ping/share/8b1fce1e39f... which shows consistent sub-10ms pings to the router from the TBB box.

I would say that, in general, 10ms is a "good" ping time, but, as suggested, there are a number of variables. You will not get that low if you have interleaving, mine generally doubles when it is on, but I have been without it for several months now, which is nice.

whats good depends on where you are in the country as well as any interleaving config, I can get 15ms to the bbc which is poor for where I am.

Indeed, one of the variables I was referring to.

depends on a lot of things

i'm up in scotland and get around 18ms to bbc.

IIRC the first interleaving DLM intervention normally adds 8ms.

Thanks guys, I'll check BBC tomorrow when I'm home.

I'm still within the first 10 days, would this 'training period' affect it?

My TBB Ping monitor has been giving me those pings, as well as showing constant, minor packet loss up until today. Where as today the pings have been consistently higher, around 32ms instead of 23ms, but I noticed that the packet loss reduced.

Kasg, I see you have plusnet, can you specifically request things like interleaving to be turned off?

No, not on FTTC and not with any ISP. It is all determined by the DLM and the only way of manually resetting it is for an Openreach engineer to request it after a visit to your premises. Someone will probably come along and say that is not strictly true, but it is most people's experience.
