Vivaciti Surfwise speed.


[link to this post]
 
Has anyone noticed when downloading a large file say a 200 mb test file with multiple threads from TBB, outside office hours that it starts off full speed for 5 seconds then seems to reduce for the rest of the download.

eg at 20:45 I did a couple of tests on Win8 and XP with the TBB test file and the above was observed, started off on meter 16.4 mbit/s then after 5 seconds dropped to 11.6 mbit/s for the rest of the 200 mb download. Throttling or QoS kicking in? Anyone else confirm? My line used to max out for the full download.

It could be to do with buffering within your IS system.

My broadband basic info/help site - www.robertos.me.uk | Domains,website and mail hosting - Tsohost.
Connection - Plusnet UnLim Fibre (FTTC). Sync ~ 54.3/15.4Mbps @ 600m. - BQM

Banger

I have the same package as you. I have raised a ticket with Vivaciti and sent them tracert / ping stats at the times I have been affected the most. That leads me to ask, is there a certain time this happens?

I seem to have problems after 17:00hrs.

My pings have settled down now but speeds are [censored].

I'm not sure I have only just noticed it tonight at 20:45 I will have to do more testing, but speedtesters are no good for this problem only large files from decent servers and then again speed doesn't reduce much. More testing needed.

IS = Internet Security, basically anti-virus and firewall.

These could be the issue if their buffer fills up at the start because they can't vet the stream as quickly as it arrives. Once the buffer is full, the stream has to stop and start as they pass stuff on out of the buffers.

Ahh now I understand. Have kind of ruled out OS and IS because have tested on a dual boot system with XP and Win 8. XP has Nod32 and win 8 is using Defender.

Heres a screenshot showing the initial fast download of XP SP3 network file 316mb

Only things that are common are router, NIC and line. Nothing major I still get files reasonably fast but something has changed as I used to get a flat line when downloading from good servers.

Edit: Thought I had cracked it, Sugarsync was uploading so thought I was saturating the upload so quit Sugarsync but still the same. Have opened a ticket with Vivaciti.

Here's a trace to TBB but with routers nowadays not prioritising pings I dont know how useful it is.

Tracing route to www.thinkbroadband.com [80.249.99.130]
over a maximum of 30 hops:

1 <1 ms <1 ms <1 ms home.gateway.home.gateway [192.168.1.254]
2 36 ms 37 ms 36 ms hg03-gw.tn3.o-bit.net.128.107.77.in-addr.arpa [77.107.128.119]
3 36 ms 36 ms 36 ms abr01v9.tn3.o-bit.net [77.107.129.49]
4 36 ms 36 ms 36 ms 77.107.128.252

It does now beg the question, do we need some other form of test to ensure that we have a valid connection. I have no idea what that could be.

Does this only happen when downloading from this site? or does it happen with others too?
