I'm getting something new now with the new patch.

Packet loss. 11 percent even.

This is not my side of the problem because I haven't had it for months with SL although I had it some patches ago.

I don't suffering packet loss in other efforts to contain games or sites on the Internet.

Is the new patch squeezing the portals shut again?

What are the ideal settings then and can we get the walk-through?

Prok, is there a specific time when you get packet loss spikes like just after opening an inventory folder with a lot of stuff in it, or performing an inventory search? I'm finding that I get hit with natsy packet loss and lag spikes whenver I do either of those things. If any of your inventory folders have lots of items (say 100 or more) try splitting it up into lots of subfolders so that no single folder has more than 15-20 items. That helped me a lot. I still sometimes have to relog after using the inventory search though.

Packet Loss

When I get high packet loss it means my ISP is acting up. Just gotta wait it out.

Packet loss is there regardless of whether I do anything in inventory or just hang there, whether on fast sim or not.

Very annoying.

Can't be related to ISP. Because I have the same ISP before the patch, no problems like this.

ProKofy,

sounds similar to what I am experiencing. This started early yesterday for me. Currently I am running on 108% packetloss (?!)

Here is the tracroute - as you can see it seems to be stopping once it gets

Im in the UK. Where are you? This has never happend for me before. I have contacted Lindens, emailed the support and have not heard back anything yet.

Your guess is as good, if not better, than mine!

I know there are a lot of very smart people out there, what do you all think about this issue???

File a trouble ticket with your ISP, hopefully they'll bug the one upstream until it gets solved.

Or switch to a different ISP :)

You could also try ip release / renew if they have some multihoming going on. certain bgp routers are more traffic latency aware and can switch you accordingly.

Not sure if LL has budget / skillset for that, though.

light at the end of the tunnel?
04-21-2005 17:26
so you think it is trouble from my ISP provider rather than something happening over in san fran area?

thanks for the replies btw. going a bit delirious with asking this same question over and over and getting no answers until you came along!!!

Actually it's happening with savvis.net, which is not your ISP but rather someone your ISP peers with.

Can't be related to ISP. Because I have the same ISP before the patch, no problems like this.


I have to agree with Prokofy. Not only have I changed nothing on my end, I have talked to several people who are having the same problems, and we are not on the same ISP. Since 1.6 was implimented, My packet loss has increased each time( as high as 150% now) . I can't even pull up Events menu!
Please, you PTB, help us before we drown in packet loss! :)

I also experienced constant packet loss (last night) after the patch. I have never had packet loss in SL, save for a few spikes here and there. This was constant and I was freezing up. I have yet to log in tonight to see if it is still occurring.

Please,

if you have packet loss go to cmd and type "tracert secondlife.com"

it could be everyone is getting routed through the same peering provider and if we have multiple complaints perhaps LL could get level3 to bug them.

If you don't do a traceroute than you only have yourselves to complain about packet loss.

I have been kicked off AGAIN and can't get back in.

So I can't check my packet loss. Guess I'll troll the forums.

Thanks for the suggestion Blaze. I just traced it. Looks like the problem is on my ISP's side. :(

https://secondlife.com/tiki/tiki-index.php?page=Experiencing+packet+loss

They wrote a good technical FAQ on troubleshooting packet loss.

Run through it, if it doesn't turn up anything, email [email]support@secondlife.com[/email]

They've gotten pretty good at responding to these problems -- mine finally went away after a couple months of irritated complaints on my part.


Also, tracert is a good general indication, but tracert is a single pass entity. MTR as referenced in the wiki topic (WinMTR in this case) uses the same mechanisms as normal traceroutes to do path discovery, but uses a continuous polling fashion, so you can identify trouble over time. It's much more helpful in instances like this.

I've been away from SL for a few months so someone's going to have to help me out a bit here.... but is the graphics and network code still running in the same thread in SL? I know this caused HUGE F*&$ing headaches for me and others in the past and I'd be REALLY surprised if they've fixed this yet.

My gf started having sudden packet loss problems after the 1.4 update last year and EVERYTHING from the SL logs and debug info in the client made it look like she was suffering from insane packet loss.... After LL blamed her ISP for weeks and flat out told me that there was no way her graphics card was the problem, I finally broke down and swapped her card out to see what would happen. Viola! All the problems went away. Moral of the story: just cus you're seeing huge packet loss, there's a chance your connection may not be the problem.

Anyway, good luck with finding the source of your troubles... I'm off to try to fix my own now ;)

   WinMTR - 0.7. Copyleft @2000-2001 Vasile Laurentiu Stanimir  ( [email]stanimir@cr.nivis.com[/email] )


Here is the report given by the WinMTR program but this is only showing 1% packet loss when in the game I am receiving between 15% and 50% packet loss every 30 to 60 seconds. Is there something wrong with my settings, perhaps even my network card that is causing this?

My packet loss issues only started since the 1.6.4 patch yesterday.

EDIT: My connection is a 1024/256 Wireless broadband connection running directly to my single computer.
