My New Pc Specs

[spine]

That is a serious set up mate, I thought I had a nice system

Have fun

Mick which ISP are you with ?

With ADSL you are limited by how many people are connected to the DSLAM, how many DSLAMs the ISP has and the size of the pipe from the Exchange back tot he ISP POA. Then you are limited by the Internet bandwidth that the ISP has. Most residential ISPs run between 100- 1000:1 contention ratio. They also run traffic shaping and Proxy servers to ensure that most things run quick.

The Optus cable I have is the quickest Internet I could find at home, although I will be going ADSL2+ when I move next month.

Mate can you post it in Dutch it may make more sense to me.

By the way the important part, how good is it for looking at porn?

Give it two weeks and this system will be old news

[mickq]

Nope, it wont be. Better quad cores arent out until much later next year. Faster RAM has been demoed at some IT shows but not available for an unknown time. The video card is by far the fastest and there arent any faster ones planned yet as this one wont even begin to stretch its legs until DirectX10 comes out and is widely used. Until then, there is no reason to make a faster card.

Im with Bigpond. Connected to an ASAM. The ASAM is fed by a 155Mbps fibre which eventually connects to a 10Gbps DWDM connection and then onto the Telstra backbone which has enough overseas and local internet bandwidth to handle anything this country can throw at it, and then some.

Unlike most ISP's, Telstra doesnt really have much of a choke-point that is a bottleneck that ruins the download speeds. Most ISP's use Telstra's (or their own in some instances) DSL then it hits a massive bottleneck when it meets the ISP's connection to the internet on their premises. Those connections they tend to make as small as they can get away with as the more they use (or the faster it is) the more it costs them. This is particularly true of smaller ISP's where the net access is a huge chunk of their total costs.

There is no traffic shaping that is less than the connection speed you pay for at Telstra. So if you have paid for 8Mbps they dont shape you down to a slower speed further up the chain unless you have hit your download limit for the month. They also do not use proxy servers as far as I know...its a pure internet connection.

The main problem with cable is that it is shared. When its running at full speed its great (but still variable in speed normally). But the issue is that you can have well over 500 houses sharing one 10Mbps or ~100Mbps cable, depending on which provider you are with and which area you are in. So if its peak hour, it tends to slow down in many suburbs. If you are in an area that has a lot of cable internet users, it can slow down a ton in peak hours - I have seen 20-40KBps on a connection that off-peak does 1.2MBps.

ADSL has recently overtaken cable in Australia in terms of speed capabilities both maximum peak and stable throughput. Not only is it capable of faster speeds that currently available through cable (24Mbps for ADSL and 17 or 20Mbps for cable) but the architecture means you arent sharing with your local users down the street. The sharing starts at the exchange where the pipe is normally lots bigger than the local street's pipe so you are much less likely to be impacted by lots of users slowing down the average speed.

Last week I did a download test with a friend one suburb away (He is in Elsternwick in Vic). Saturday during the day. I downloaded a large (400MB) file from a US based newserver, and got my normal 888KB/sec stable (it can peak higher) dowload on my 8Mbps ADSL. He downloaded the same file at the same time on his 17Mbps Bigpond Cable connection and hit only 350KBps. Reason being his connection was shared with local houses and obviously others were online and downloading. All it takes is one kiddie up the street (or within many hundreds of houses where you live) downloading warez and it impacts on you.

The same happens on some non-Telstra ISP's. Most have a choke point that is their internet connection, so its irrelevant how fast your modem connects to your exchange other than for marketing puposes (24Mbps sure sounds great!) - the data from the internet slows down through the choke point at peak times as lots of people are trying to get access to a small pipe so everyone gets a small slice of it.

Unlike cable, I have never - not even once experienced anything less than full speed on ADSL 24/7, and I have been using it for 6 1/2 years now in three locations. However those using other ISP's I have found typically can not say the same - many slow down in peak hours.

Its worth noting that some smaller suburbs with many fewer users wont have a 155Mbps fiber feeding their CMUX/ASAM/DSLAM so may be a bit more susceptible to slow downs caused by others in their suburb - but this is typically a small percentage of users. Then there are the new ones which are even better and have the brand new equipment....gigabit speed instead of just 155Mbps.

I gave up buying the best of computer equipment a year or so ago. I find it doesn't matter how much you spend or what brands you get, you can still have trouble with them.

They also depreciate quicker than a BA Falcon.

But I must say....nice setup.

Give the sparse nature of the groupings of residential users, you'd find that not all CMUX, ASAM, or DSLAMs are connected to 155Mbit fiber fed exchanges. Take a microwave fed integrated RIM hut with remote CMUX ports (hardware lives in parent exchange, prime example of one we have here in WA from CANN being the parent node and Roley Stone being the exchange) for example that both share the same bandwith. Or even an average RIM cabinet with a mini mux or non-attached CMUX/DSLAM. These situations are more predominant than I suspect you may think.

You love talking in French dont you newl.

(Sorry to all the French)

mmmm.... maybe not.
