Weird request, but I need a NZ based server that has a decent internet pipe into it so that I can stress test the upload capacity of a Snap fibre connection used to stream live video. Ideally I would be able to upload two or three 500MB files tomorrow, to a server that has a relatively large download capacity so that I can test actual connection throughput.

Any suggestions on better ways to test the connection welcome, we generally would like to be able to get two to three consistent streams of 8-12Mbps each simultaneously to three separate locations, which should be easily achievable, but this connection is suffering an unidentified issue. This connection is on school property in Burnside, and is (AFAIK) a 100mbps symmetrical fibre service, authenticated using Snap's Prepay service.

Snaps support suspect something onsite, but there is supposedly no equipment between our router and the outside world. Our router does have a limited throughput of about 70mbps, but we are seeing speeds of up to a 10th of that.

Hello... Our robot found some keywords in your post, so here is an automated reply with some important things to note regarding broadband speeds.

If you are posting regarding DSL speeds please check that

- you have reset your modem and router

- your PC (or other PCs in your LAN) is not downloading large files when you are testing

- you are not being throttled by your ISP due to going over the monthly cap

- your tests are always done on an ethernet connection to the router - do not use wireless for testing

- you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

- Your ISP and plan

- Type of connection (ADSL, ADSL2, VDSL)

- Your modem DSL stats (do not worry about posting Speedtest, we need sync rate, attenuation and noise margin)

- Your general location (or street)

- If you are rural or urban

- If you know your connection is to an exchange, cabinet or conklin

- If your connection is to a ULL or wholesale service

- If you have done an isolation test as per the link above

Most of the problems with speed are likely to be related to internal wiring issues. Read this discussion to find out more about this. Your ISP is not intentionally slowing you down today (unless you are on a managed plan). Also if this is the school holidays it's likely you will notice slower than usual speed due to more users online.

A master splitter is required for VDSL2 and in most cases will improve speeds on DSL connections. Regular disconnections can be a monitored alarm or a set top box trying to connect. If there's an alarm connected to your line even if you don't have an alarm contract it may still try to connect so it's worth checking.

I recommend you read these two blog posts:

- Is your premises phone wiring impacting your broadband performance? (very technical)

- Are you receiving a substandard ULL ADSL2+ connection from your ISP?

I am the Geekzone Robot and I am here to help. I am from the Internet. I do not interact. Do not expect other replies from me.

What sort of router are you using? Would FTP access be suitable for your needs, or do you have another transfer method you're hoping to use?

FTP should be fine, our router is a Draytek Vigor 2110, authenticating the Wan using PPPoE. http://www.draytek.co.uk/products/vigor2110.html

Just FYI, the Vigor 2110 won't be able to keep up with a 100 Mbps connection, you'll probably get 75-80 Mbps with it. The 2130 is the model generally recommended for UFB as it's capable of up to 900 Mbps.

Mentioned limit in first post, well aware of it, and are more than happy with it at this stage, but not with upload of 7Mbps.... Download sits at between 60-70mbps just fine.

Woops, missed that bit. FWIW here's a test from a 2110 on a 100/50 Snap UFB connection

Our Current test... Streaming HD 720p Video to three locations with 2Mbps stream each is painful... Not really what we want... three or four times that is a nice place to be for HD.

Cheers, quick test from home on ADSL and the server is receiving at line speed, so it should be a good indicator, will post back tomorrow after some tests whether I find the cause/the rest of the speed :-P

So some quick testing and focussed isolation found that the Draytek was definitely affecting upload capacity, and after digging through all the menus, traced the issue to the QoS, and buried a few menus in the unconfigured QoS was activated, forcing all traffic into a fraction of the full capacity.

Back to my expected (on average) 75Down/60Up Connection and happy.

Uploading at 5.5MBps to Auckland (a healthy 44Mbps), thanks Inphinity

Glad you got it improved :)
