Can anyone tell me what is an acceptable level of jitter on a 50 mb line? Using pingtest.net more often than not the jitter is more than 50% of my ping level. 0 - 2% packet loss, 20-30 ms ping, 15-30 ms jitter. Playing any of the COD games is a nightmare with lag, and Black ops is particularly bad.
If this isn't the problem what else could it be?

i have had to give up playing Blops because of loss and jitter. I was teleporting all over the map, most servers would ban me if an admin was on.

you sort of answered your own question, you know 15-30 isnt acceptable to you.
whats acceptable to VM I think any jitter is, they tend to only look at speeds when diagnosing problems.
I always strive for extremely low jitter sub 2ms, realistically I found anything below 10ms not that noticeable on my daily activities, but 5-10ms is noticeable when testing (looking for jitter). 10-20ms is noticeable by accident on my daily activities but not serious. Higher then that tho and its enough to really frustrate me, generally also if I see jitter higher then that speeds are usually also affected.
The only way round it is maybe artifically increasing your latency as 15-30ms jitter not so bad on 100ms latency as it is on 10ms latency.
Now I have always assumed high utilisation is the prime cause of jitter on VMs network but I am currently scratching my head as craig got his utilisation figures and i got mine, officially my utilisation is 10% lower than his but I have significantly higher jitter.

Guys, thanks for all your posts!!!
I did what you suggested and ping'd the bbc (i did it 3 times).
Stats for: 126.96.36.199
packets sent 250, received 250 Lost = 0 on all 3 pings.
Round trip time in ms Min = 11ms, Max = 116ms, Ave 24ms
Round trip time in ms Min = 11ms, Max = 96ms, Ave 26ms
Round trip time in ms Min = 11ms, Max = 115ms, Ave 23ms
I play COD via the xbox which is hard wired to the Superhub. I have set up port forwarding and listed the primary and secondary DNS servers. I have also installed the game on the hard drive. With each progressive release of COD over the years, the lag has got progressively worse. In order to improve it i subscribed to the 50 mb service as i was told it was on a different network to my old 20 mb service - There has been minimal improvement. I live in London (Battersea), and I know my area has high utilisation rates so there are periods of the day when it is really bad, and others when it improves, but it doesn't improve that much - i guess over the years more and more people are using Virgin?
I did read the other day that Virgin have been misallocating / incorrectly assigning COD B'ops traffic which they said they have fixed. Anyone know anything about this?
Any ideas? Is it worth approaching Virgin with this or will they just laugh?

Jitter seems to be inherent on cable connections. makes me wonder about their advertising as the best option for gaming. It obviously isn't.

I think COD and WOW was mixed up with p2p traffic, but that is likely fixed.
The only thing I can suggest is to set up a ping monitor to track when you experience the congestion.
Jitter is the variance of the min and max ping.
I believe that VM suffer from it due to their network management issues, but I know of many VM users who don't have issues, and therefore this can only be down to the local UBR being overused or overloaded.
My friends connection
As you can see above, my friends connection is fine with max pings constantly under 60ms
He lives 5 minutes from mine but on a different network segment.

We can't see from the above as you have posted images whicn need to be cleared by a mod in Canada.
Load them to a site like photobucket and reload them to here as from another site and all will be well.

I am sorry to hear you are having this issue with your connection.
Could you please let me know if you are still having this issue?
