GeoffisPure: Setting a max download speed of 500K and 250K still resulted in the unusual pattern and only made the downloads take longer. :(
wjw:
Are you still doing these downloads on wireless?

Regs: have you attempted to hack your TCP parameters - like MTU, RWIN etc - to make your connection better in the past?
do you still get ping drops from a wired connections?
have you a spare DSL router that you can swap to and re-test?
what dsl router are you using?
Time to find a new industry!
webwat: Since this is normal behaviour to some extent because its the nature of TCP, I wonder if there is anything else we have missed by focussing only on the TCP backoff issue. This behaviour would certainly be more apparent if something else was slowing down the throughput. What speed is your ADSL connection syncing at?

richms: Mine doesnt do that on snap, but without a time scale on the graph its pretty meaningless.

webwat: Also, does your download program measure speeds in kBytes/sec? In which case your 500kB/s download translates to 4000kbits/s ? quite a reasonable speed that implies your issue only occurs with international traffic at the 4pm peak time that you measured it. Traffic to Oz has lower latency than other international, so it may be caused by international latency as much as anything.
Talkiet: I'm strongly suspecting an ISP issue in this case. I'm normally the last person to actually suggest this - expecially in the case of Snap, but I really think it's worth pointing Snap at this thread via twitter and asking them to confirm that it's 100% not them.

Please give me advice, fellow geeks. What should I do?
