Sim crossing (Rubber Banding) worse for friend than me?

Someone I know has a parcel right on a sim boundary (so do I actually, but that's neither here nor there!)

They expressed annoyance on the sim crossing experience they appear to suffer, not just at their home, but everywhere else too.

Last night I carried out a few simple tests, (myself I only carry a small simple AO hud) and no "bling" or much on my avatar, so I'm quite "clean" you could say.

I got my friend to remove al their HUD's (they normallyl have 3) and a couple of very small bling jewelry.

Even in this state (Just their bare, clothed avatar) they are suffering much worse "rubber band" sim crossing than me.

they would carry on walking up in the air, or thru some rocks for about 3 to 4 seconds, whilst for me with a simple AO hud on, I only suffer this for about half a second, at walking speed, almost unnoticable really.

I loaded myself up with about 5 or 6 HUD's and as expected I got a large delay, though still only about the same as my friend with a bare avatar.

As I said, my friend says they get this wherever they are (not just at home)

I then got out the Statistics Bar and we compared numbers when looking at the same view, and there was not a LOT of difference.

Their PC is a Triple Core AMD machine with 3GB Memory and a GT120 Nvidea graphics, all pretty new stuff.

I'm not sure what Internet provider they are with but the Bandwidth and Ping numbers on the statistics were about the same.

So, I'm kinda puzzled why they should be experiencing much worse sim crossing delays (rubber banding) than I am?

Anyone else got any ideas?

Or any Tests (PC or SL based) that might show up a possible reason?

Thanks.

my first guess would be that your friend is on a different asset server then you, maybe one in another colo if LL has their assetservers distributed.

But... what assets? AFAIK, a sim only cares about stuff that's rezzed in-world when an agent arrives in it. There is (was?) a popular hypothesis that Inventory could have something to do with sim arrival, but I don't think that's true (it would, however, give an excuse for the asset server to get involved).

I'm not entirely sure about the methodology of the test. I'm assuming Piggie is observing both avatars; seeing another avatar lag and not your own could be a function of what order the sim gets around to providing an update about agent location--maybe it's quicker about it if it's the agent associated with the viewer. So, the question would be if the friend also saw Piggie's avatar correct itself faster than their own. (Unfortunately, I suspect that's the case anyway, which puts us back to square one.)

I'm not completly sure about how sim handovers are handled in the current grid setup, the only thing I am pretty sure about that the assets server is likely the one system that is split over different servers based on account.
The login server only comes in play during login before handed over to the assets server and grid server, the grid server hands over to the sim that pools the assets server for clothing shape and attachments as far as my information goes.
from what I can figure out border crossing is handled as a partial logout, you connect to another sim that needs to know what you are wearing and for that polls the assets server and then signals the previus sim to disconnect completly.
if the sims exchange the clothing shape and attachment data directly then the assets server would not be involved but then the only variable big enough to make a distinction is the number of scripts and the OP's friend was not wearing anything scripted and had worse handover timing..
textures should not make a difference because the sim already has that data as do all viewers in view, afterall there is only one texture cache holding all textures like clothing layers, baked textures and prim textures both from it's own agents and child agents.

Thanks for the answers so far (I love this techy stuff)

My friend has been finding this happening to them for some time now.
Days/Weeks (not sure about months)

Says it happens wherever they are on the grid, just very slow "positon update," (for want of a better phrase) when they cross sim bounderies

I "Normally" don't have issues harldy at all when walking, a little twang of about a metre or two and that it.

In a fast moving boat I always get the oddness of viewpoint swing round, boat goes of ina weird direction, then a couple of seconds later, they boat it back where it should be.

Or the flying (faster than normal) thru the air, and from time to time getting stuck in a long long flights across multiple sims before springing back to your real location.
This can be a LONG wait sometimes, but as I said, sometimes I may be travelling way way faster so I'm not blaming the system as it's me doing things "non standard"

The test last night was both in the same location. looking at each other, and me seeing myself with only a 0.5 second spring back (rubber band effect) when walking over the sim line, but my friend (with no attachments) seeing themselves carryingon walking into solid rock (or into the air) for about 3 or 4 seconds before springing back, and myself witnessing it also.

"Rubber banding" is due to the client assuming you continue to move in the same direction and speed until it finally gets an update that you stopped or changed direction.

The message that updates your movement is sandwiched in amongst all the other data packets going back and forth. Perhaps her internet connection has some choking or delay in it? Or she has other stuff running thats using up her bandwidth? It can even be malware you dont know about eating resources in the background, or that Windows search tool doing indexing, or something like that.

/me nods - what's the friends Packet Loss look like? Are they on wireless, which is notorious for this sorta thing?

I have a really naff internet connection, due to my geographical location, and I get this rubber-banding effect quite often. I can pretty much guarantee that when it's happenning, my connection speed has dropped to under 1.5mb/sec.
