HSDPA Tweak

The file was cached by your browser - thats why you had 80mbits. Changed registry as described above with reboot. No performance increase. XP Service Pack 2.

Cached before I opened the site? :confused: It was the first Gamco test I did.
I refreshed afterwards and the speed was a normal 320Kb. Anyway. (BTW, I know my speed wasn't really that fast, it was just sorta funny and unexpected to get that result)

Cool, registry it is then.
I'll try tonight. Already have SP2 though.

I'll report back in a few hours.

Hey Geriatrix!

Try the reg tweak mentioned at the start of the thread. I did this tweak to a WinXP Media Centre Edition with SP2, my benchmark was mentioned on pg 1 I think.

Good luck.

PS: V3G - Spoke to my mate about the LineBoost software he was using, he said it works but can't tell me what settings were changed, apparently it is a very simple thing, you turn it on or you turn it off.

Okay, I did the registry tweak. And all I can say is wow. :)

Where my tests used to be(as in today and yesterday) about 320 - 360 Kbps, its been between about 450 and 800Kbps afterwards!

Seems to work. Thanks guys!
 
first post tweak for me (registry). My mate bought the program from bidorbuy, not sure how his improvement rates to ours.

OK, I'll test this.

These settings change the TCP window window size and will affect how the TCP sliding window performs. The larger the setting the more data will be downloaded before handshaking takes place. This will improve download performance, such a a FTP of a big file.

The downside is when the connection is not reliable, the whole transaction must be redone and you'll end up with a even lower throughput than before.

So bigger is not necessarily better. You need to find the optimal size for your specific connection. And this will change all the time. Clever IP stacks will manage this automatically.

The sliding window will not affect latency, especially as measure by a ping. So any improvement in ping times is due to something else.

I'll go through all of this and build up a set of recommendations. Unless someone else have already done this? (hint, hint...normal virtual beers apply...;))
 
I can confidently say, yes. Even though the increase is marginal and not drastic.
Latency however is still the same and because of that, it creates some doubt
about the increased performance. :cool:
 
now you can all download a 700mb DivX video a pay a k*khuis vol geld vir vodacom :D

As I posted above, increasing the TCP sliding window will improve download performance on a good quality link, but will not improve latency as measure by a single packet ping.

Latency and throughput are two different parameters and are not always related.
