Is this normal?

Hi all, apologies if this kind of thing gets posted all the time, but I have just switched from BT to Vodafone full fibre 900mb. I have taken the below trace. I can see the min
latency, but also regular spikes of maximum latency. Not sure if this is bad or not? Any help much appreciated.

Out of interest are you constantly hammering your broadband connection which could be the cause of these max latency spikes? I am also wondering if you have a router that manages buffer bloat via good traffic shaping.

Thanks for replying to my thread. I’m not aware of any hammering of the broadband, only my daughter keeping on top or social media, but she has been out all day so no traffic from her.

I have an asus RT-Ax86u router, not sure if this adds any traffic shaping,

If it does not sure how to set it up. Any help much appreciated.

Thanks.

You could try this bufferbloat test tool

Waveform bufferbloat tool

You say you switched from BT to VF - was the previous connection with BT on FTTP also?

If so do you have any previous BQM comparators for the same box with BT? That would probably the easiest way of seeing if it's the box or the service.

I suspect it's the service, although perhaps a touch unfair on VF by me but hey ho.

Hi, thanks again for your suggestions.

I’ll run a bloat test later today and post here.

Sadly I did not take any measurements from the bt service so have nothing to compare.

I do have some speed tests from the routers wan port from both. I used the same router for both providers.

BT - Average speed 850-910, ping times 8.0-9.0ms.
VF - Average speed 850-920 ping times 15.00-19.00ms

No new services since the upgrade are running. Exact same services.

As I’m in my 14 day cooling off period do I jump ship, and go elsewhere?

???!

Sorry, but what actual *problem* do you observe when using the service, other than a trace of yellow on that graph?

The yellow line is the 99th percentile latency: 1 in 100 packets suffer that latency, so the other 99 packets are faster. The blue line, if you can see it, is the average latency. AFAICS it's overlaying the green line, which is the minimum latency (1st percentile).

If 1 in 100 packets take an extra 10ms to be delivered, I certainly would not notice this. I would rate price and customer service much higher.

If this were an indication of congestion in Vodafone's network, I would expect it to get much worse in peak hours - but it isn't.

Also remember that this is measuring the response time to incoming pings. Your router may simply be deprioritising ping responses when it has other things to do, or to save power. Are you using the same router as you did with BT? If not, then try using the other router and see if it makes a difference.
