Adsl vs fibre latency

Hi lads
I just moved to Zen recently. Have adsl at the moment.
PING bbc.co.uk (212.58.246.104) 56(84) bytes of data.
64 bytes from fmt-vip133.cwwtf.bbc.co.uk (212.58.246.104): icmp_seq=1 ttl=56 time=18.7 ms
64 bytes from fmt-vip133.cwwtf.bbc.co.uk (212.58.246.104): icmp_seq=2 ttl=56 time=19.2 ms
64 bytes from fmt-vip133.cwwtf.bbc.co.uk (212.58.246.104): icmp_seq=3 ttl=56 time=19.9 ms
64 bytes from fmt-vip133.cwwtf.bbc.co.uk (212.58.246.104): icmp_seq=4 ttl=56 time=19.4 ms

It's all right and I'm happy with that. Do you think changing to fibre may lower my latency down to 7-10ms? Wouldn't that be risky? If I change to fibre and interleaving will be applied then I would be in 12 month contract without an option to turn it off.
My cabinet is around 100-150m from my house.
Thanks for any suggestions.

It might, but it might also raise it.

If latency is so critical to your connection, get the fibre installed on a new second line to retain low latency from ADSL2+.

Latency is primarily an issue of backhaul, and not the local connection, In principle VDSL has a slight advantage over ADSL, although such minor differences can be obliterated by interleaving.

For the most part latency will be down to the route by which your service provider connects you to the destination and if there is significant congestion.

I just had Zen fibre activated on my line (400-500m from cab) and get 7ms to BBC... used to be 10ms before that with Plusnet Fibre...

It also depends where about in the UK you're based and the routing it takes back to Zen and then to BBC...

I would say you would see an improvement but theres always risks.

Thanks
Might give it a go.

In my experience no, latency between adsl and fibre is no different.Your latency figures seem pretty good.

I am on Zen via WBC and I get 14.

Well I get 62 ms on my fibre line

I get 61 ms on my adsl line

I'm on the WBMC.

So you are doing great.

Could you try pinging the BBC via command! I don't find the TBB tests ping to be very accurate

it would appear so although I do nothing that requires any sort of good ping/latency.
