How about "Slow's Good". It's really been worse lately, and the Youtube video speed history page pretty much confirms it for me. This reminds me so much of the 8-bit days: Click play, go and have a cup of tea, come back later and it might be finished. Thanks for the nostalgia trip Telstraclear.

So a friend linked me an 8 minute video half an hour ago and so i began buffering it. I forgot about it and checked it just, and it STILL hadn't finished buffering (~85%)

That cache can't come any faster.

Somebody should come up with a GreaseMonkey script or something to put those flashing colour screen borders like the C64 had when "fast" loading :-)

anyone mentioned Packet Fragmentation settings on you computer and router ?

less time putting small peices together

stream the file gets started and then the caches send a big hit , but your router is too busy with its setting of MTU which is an average low, to make network latency look good.

so the large transmission get cut up into smaller sizes for the home lan settingin the router, taking time then the pc has to rebuild it, which you see as buffering, with stop go playing?

just an idea, max size for ethernet is listed in wiki somewhere,

sleemanj: Being entirely hypothetical and ignoring "don't be evil" for a moment, one would expect that if Google were to radically throttle traffic to "non-cooperative" ISPs, that it would be in their benefit by way of "encouraging" pressure on the ISP form it's customers to GET cooperative.

If an ISP has a pathological dislike of peering, and isn't keen on running a cache then you'd expect that Google would find that to be a very non-cooperative ISP.

You would expect that Google could continue to put pressure on an ISP in this way until the ISP gives in, or loses it's customers to a more cooperative competitor. Either way, Google wins.

I can't see this being the case. Given that Google has said publicly they can't turn on IPv6 access to the Google sites for all because it might impact the 0.2% of the Internet which have IPv6 enabled but broken access to Google via IPv6, and that is too high a risk, I really can't see them deliberately doing this on purpose - especially since TelstraClear bound traffic will be such a minor amount of traffic for them - that they are most likely dumping into TCL's upstreams via peering anyway.

No. Sorry - but this is just totally wrong and unrelated. The MTU of your PPP interface will be at, or close-to, the "internet default max" (of 1500).

^^ whoopsie I don't know what I did there! Pls delete :)

What I was going to say was: how about those old "Invade-a-load" things they had on the C64 cassette games - a quick blat of Space Invaders whilst waiting for the game to load.

I've all but given up on watching youtube videos on Tesltra now.

i think ive noticed setting mtu to the maximum from default an improvement, of it is close to max the it still has to resize them, and who knows what the router manufactures think is a good default setting between them, my manufacturer recommends (asus) on there site having it set some between 45-65% which is not any where near the max 100% really, but did say the default, each to there own i say, something to look into

You are quite welcome to do whatever you want to your own CPE and devices, but please don't offer quite bad advice that people might follow to their ultimate detriment.

Considering you are not going to get anything higher than 1500 B on a broadband PPP connection in NZ (or pretty much anywhere else), this will make no difference. I would be extremely surprised if the default on any device was anything much lower than about 1400B - which really only adds overhead to the BRAS and the sending node, not to your end device. Fragmentation reassembly at the typical packet rates of broadband is negligible - even a 386 PC would be able to handle it.

I would be really stunned if you could actually prove there is an improvement from messing with your MTU settings - it will very likely bite you quite badly, as well.

+1, in NZ if your on ADSL then PPPoA will mean 1500 is the correct figure, if you are on Telstra Cable, then its static IP no PPP connection is used, so no issue, the correct answer is 1500. Any other ISP via PPP that I have dealt with in NZ (ie some apartment buildings with FTTP then ethernet disturbution) have all been stock standard PPPoE so 1492 is the answer, nothing else.

well it seems to work 4 me, im just a rookie, im watching hulu at 1.3mb/s on xnet with only 3 or 2 stops max on a 20min show, i like to keep my computers processes clean,

but apparently im wrong, i leave it up to ppl to do there own research no point having fast internet if there is all sorts of errors in my computer interrupting the stream and getting the isp blamed

Err, you're watching Hulu? Isn't Hulu restricted to US only. Which would mean you are very likely using a proxy. Which would mean you are very likely avoiding the entire TelstraClear to Youtube issue anyway.

I haven't tried through a proxy because I do not have one to use currently, but I have no particular reason to believe that it would suffer the same Youtube affliction.

And hang on again, you're using XNet? You do realise this is about TelstraClear right, particularly TelstraClear cable (I don't remember if their ADSL connections are also afflicted)??
