it's not the network latency which is the governing factor Wink

Well, the present variability is definitely visible in ping for me, anyway. More than that, I do not know!

i do feel there isn't a lot to gain from maraDNS over Unbound as you say

Yes, I absolutely agree with you, 30FTTC06. Your Unbound setup seems to work extremely well, and extremely well with the Raspberry Pi. There would be no sense in using Mara instead. The comparison is interesting, though, and definitely worth doing just to see - thank you for going to all the trouble.

I like the idea of it not expiring, but i'm not a big user a windows so maybe not for me, but it's another one for the pot for sure.

I'd prefer something which runs on the raspberry pi rather than on the local machine.
I'm not too good with linux so I'm struggling but "pdnsd" looks promising.
http://ubuntuforums.org/showthread.php?t=331850
Don't know if I can make it run on the pi.
Also I'm not sure if it refreshes out of date cached items in slack periods like Acrylic.

Re: Dns seems high

Thanks.
It's all the other bits like config and testing that discourages me from getting on with this - All those strange linux commands.  Cheesy
Please let me know if you give this a try.
Before that, my next pi project is to turn it in to a wireless access point. The objective is to configure the BT fiber modem as a router and let the pi do the wireless.

Re: Dns seems high

Are one or more of the plusnet DNS servers performing much worse again tonight? I'm not seeing any packet loss from ping, but far more timed out (no response received) dns queries than usual.
These were the overall stats over about 2 weeks up to and including Sunday 22nd September (0.58% failure rate):
[tt]dnsmasq[295]: server 212.159.6.9#53: queries sent 10711, retried or failed 63
dnsmasq[295]: server 212.159.6.10#53: queries sent 63, retried or failed 0
dnsmasq[295]: server 194.72.6.57#53: queries sent 0, retried or failed 0[/tt]
These are the stats starting from about 5:30pm today (13.9% failure rate):
[tt]dnsmasq[296]: server 212.159.6.9#53: queries sent 194, retried or failed 27

Re: Dns seems high

The DNS seems to be a bit more stable this morning, if significantly elevated. Pings still most jittery, though.

I'm closer to 20ms.  Undecided

@npr
It was 3ms  Sad    Cry    Wink    But be not consumed by thine envy, for there are some at PlusNet Towers who wouldst have thee believe that 16ms maketh no difference to anything, and verily mine web browsing experience is in any case no better than 6Mbps ADSL at best - which is a bit carp, I think you'll agree.
It's amazing how, with the noise of xDSL removed, you can actually see what's going on from single millisecond changes, even if practically speaking the millisecond doesn't make a difference in itself - often they are an indicator of something bigger which does make a difference. My connection is incredibly stable usually, so if the ping moves from 3 -> 4 -> 5 ms, something has definitely changed. And if it jitters around all over the place there is definitely a problem.
The fact that all the other FTTP metrics are so good (or were) makes the comparatively poor browsing responsiveness the more surprising (and irksome!) How can I boast to my friends when their ADSL connections are certainly no worse? I have to focus on the fact that we can stream YouTube, Netflix, LoveFilm, iPlayer, ITV Player, 4oD, whatever Channel 5's is called etc. etc. all at the same time, no problem at all. But it's really hard to concentrate on so many video streams at once    Grin

I think pings in general have been higher in the evenings for the last few nights. Have a look at the TBB graphs - something isn't working properly or has changed.

I've got plusnet superfast fiber which connects at 20 mbps down and 0.6mbps up -- on a good day.
Yesterday the BT speed test was showing around 6mbps down and 0.01mbps up.  Angry

Re: Dns seems high

Quote from: AndyH
Quote from: ejs
Are one or more of the plusnet DNS servers performing much worse again tonight?

I think pings in general have been higher in the evenings for the last few nights. Have a look at the TBB graphs - something isn't working properly or has changed.

Yesterday evening looked like a new dns server specific issue - there was no problem with icmp ping times to the dns servers, with zero packet loss, yet leaving ping running while repeating dns lookups in a loop, about 10% of dns queries timed out.
