Circadian Lag

Has anyone else been suffering from the following problem....?

I have two lives on SL. In my mornings (UK), I have very little in the way of constraints as far as "lag" goes.

In my evenings (like now as I post this), I can barely move and even the most basic of functions takes many seconds to do, even minutes at times (if at all) - walking, talking, inventory functions, editing etc . I have already done as much as I can to optimise my settings in preferences.

This circadian lag occurs both in normal SL and Windlight.

I am on Virgin ADSL, and have checked the stats between the two times and find no difference. On SL despite the framerates being broadly similar, I have however noticed a lot more packet loss in the evenings and wonder if this is contributing. However, I'm not sure if this is coming from my ISP or from something in SL itself.

It's a shame because most of the people I interact with are on at the times I can't interact because of the "lag" constraints I have. The time I have in the mornings when I can move and do things is very nice but I spend it mainly alone....which isn't so much fun.

Any suggestions?

For those of you who are interested, I have an ATI Radeon 9700 card and use XP Service pack 2. I have a laptop with Intel Pentium 4 CPU 3.00 GHz with 1GB RAM.

However I suggest the fact that I can use SL perfectly well during my mornings means that the computer is less likely to be the cause of any problems...

could be a few things, more people on SL at laggy times, more people on the net in your area (or LL's) at laggy times, traffic shaping occuring somewhere between you and the SL servers at laggy times. any and all are possible

Are you being subject to the so-called "Fair Usage" policy?

and, perhaps better:

Thanks for all your replies!




I think you may have hit the nail on the head. I've been fine for nearly all my SL experience, but recently moved home and went down from an 8mbps service to a 2mbps service and therefore wasn't aware that they had recently changed the terms for the 2mbps to put a cap on the speeds at various times of day.

Thanks for that link, when that was announced I was on 8mbps so I never had this issue...time to find a way to go back! Not impressed with Virgin though, since I had signed up to a different deal initially...

From: someone

Like many others before it, Branson's boys are to introduce a traffic management system to safeguard the quality of its offerings from the heaviest downloaders. Unlike most ISPs however Virgin has taken a rather more graceful – and open – approach.


It has announced that during peak times from 4pm to midnight users of its 'Broadband M' service (2Mbps downstream/200Kbps upstream) who download more than 350MB over this period will find their speeds capped to 1Mbps downstream and 128Kbps upstream. 'Broadband L' (4Mbps down, 512Kbps up) users who break 750MB during this time will be limited to 2Mbps and 192Kbps. Finally 'Broadband XL' subscribers (20Mbps down, 768Kbps up) will drop to 5Mbps and 256Kbps if they exceed 3GB.


I'm sure P2P Usenet heavy downloaders will be disappointed with this news, but I would argue this approach is far more graceful than other ISPs who simply warn and even cut-off high bandwith users with little warning. This way no one gets stripped of their service, bandwidth is controlled and there's still all night to get those 20Mbps downloads roaring down.


In a perfect world the phrases 'Fair Usage' and 'Speed Cap' don't exist. In this world however this is the best solution yet.

It's more likely to be local conditions.

I find that at 2am GMT things start getting dicey, but this is when our ISP tends to run all sorts of tests etc and send updates to the router.
