Hi

I just upgraded my Vodafone Cable modem.. and now on a 50mb down & 2mb up plan.. with 80Gb..

I am getting a 30ms ping.. I would have expected at 10-15ms ping..

Can anyone advise?

Ping to where and how did you test and reason for expecting 10 -15ms ping? Very little detail in your post

It was a ping on speedtest.net. Locally to Christchurch

Thanks

Done over WiFi or Ethernet?

OK but still not sure why you are expecting a latency change? As the plan was a speed change

The reason I was expecting a change was

1. my folks on UFB.. 30/10 and get 10-12ms
2. new modem, higher plan 50/2

I just throughout I would be getting something similar..

Has speed improved? You are on Cable which is different than Fibre

Bandwidth doesn't correlate directly to latency

Different technologies have different latency, though I do recall back in the day of the paradise cable plans that we used to have single digit latency to paradise

One person supports this post

Just because you're in Chch doesn't mean that a speedtest.net service in Christchurch is actually local. If there is no local peering that traffic could easily be transiting to Auckland and back for example.

speedtest.net is also a very poor test of latency, a simple ping is vastly more accurate but and once again a ping to a speedtest server is also meaningless because you don't know how that traffic is routing. Of far more significance is latency to serers and/or sites that you actually use.

If you use the Snap Christchurch speedtest they locally peer with the ex TCL network in Christchurch, if you are testing to the Telecom speedtest server its likely hair-pinning via Auckland.

At the end of the day the first hop latency is in most cases entirely irrelevant. there may be lots of hops in between over a MPLS network that are invisible to you before you get your first result in a traceroute. what is important is end to end latency for whatever application you are using.
