I have the following ports open for the PS3, I get great speeds.
5223 (TCP)
3478 - 3479 (UDP)
3658 (UDP)
Also, I don't use wireless, not a big wireless fan, RJ45 all the way!

May I ask why?
I wasn't aware there were any ports needed to be open for the PS3.
I only have the PS3 set with a dynamic IP address, so just left it as is.
Never had a problem with the PSN Store, or the few online games I've tried.
What are these ports meant to be for?
If it's going to help/improve anything, I'll set the PS3 to a static IP, and forward the ports to it
V1N.

The ports are needed for speech and a few other things. I would need to check on my home machine what the ports are and what games they help in (i.e. I know motorstorm uses one port for lobbies etc and not forwarding them causes connectivity issues).
Depending on your router you could keep your DHCP address and still forward the ports.

Well I struggled playing some online games (The Darkness and RB6Vegas) without opening the above ports.
I could connect to the Store fine, download fine, but some games seemed to be very fussy - So checked on the Sony pages where it recommended to open these ports, did so and everything was cool![]()
But I will do it in the future if needs be.... and saying that... when we did all play Motorstorm ages ago, I never did hear any voices... maybe that's why? I'd assumed it was because it was early days, and nobody had a headset... in fact, I still don't 
Mine go at full speed for both ps3 and 360. Apart from when others are having problems (which sometimes happens on days big demos are released, but the issue is server side).
I am not on Virgin Media though.
I have a 15MB service and I get about 1.2 MB a sec download on either 360 or ps3.
Have you tried both downloads at the same time of day just to make the tests fair? I know Virgin media do throttling etc for users in the evening (based on certain criteria). I can't think of anything else obvious, only your ISP stands out as there are many bad reports regarding them.
I would try to do 2 oldish demos one after the other on the different systems as a test, then try downloading something like XP SP2 on your pc, and see what differing speeds you get (although on 360 it is bit harder to judge how fast the download is going compared to ps3 and pc).

I have tried downloading just after lunch when no throttling takes place.
I have also tested download speeds by downloading large files from newsgroups with my pc its very quick.
Also downloaded sega rally demo on the 360 thats comes down fast.
Downloading sega rally on the ps3 was very slow.
All the tests were done after each other on the same afternoon.
When i think about it my ps3 has always had slow download speeds.
The only time my 360 is slow is when a brand new demo of a much wanted game is released.
I can accept that as the ms servers must be getting hammered.
Forgot to mention my system is wired through a netgear router.
Can you try the xp sp2 link I posted earlier? That is http and I am certain the ps3 downloads are over http. I am not sure about the 360 download system.
That download should max out your connection, assuming there are no problems on your system or Virgin's end.

Thanks just tried your link and it downloads at about 2.1meg

Thanks for all your help.That's me out of ideas, I would stick a network analyser on there next (nothing fancy Ethereal would be fine). But I suspect this might be a bit excessive unless you are me.

Anyone found a solution yet?
I'm on virgin 20mb and my d/l speeds from the PSN are appalling, around 200kb/s i'd say. I use speedtest on the ps3 and i get 7,000kb/s apparently, so somewhere in the ps3 im losing a lot of speed! is the PSN always this slow as we only got our PS3 yesterday? I've tried at all times of day and it makes no difference
If it only happens when downloading from the PSN it's gotta be the PSN that is the problem.
Maybe search for a Sony PS3 forum?
