The Map Is Blank

The map we have now often doesn't work at all. In the picture below, the entire grid should show, instead, nothing shows.

The map does show most of the time, but it is slow, it is often blurry, and the private islands people have paid so dearly for don't show their landmass when zoomed ou,t although they do show a very misleading single green do,t making it look like there is only one person out there.

Certainly no reason to go visit that nearly deserted casino or amusement park, no action there.

So it appears.

Suzanne, while I experience a greater incidence of grey textures and slow loading than normal, it seems that what you are experiencing is more extreme. Is there any possibility that something has caused a slowdown or congestion of your internet connection? It could be anything from stepping on a network cable, to a broadband router overheating, to a bandwidth-hog neighbor if you're on a cable modem. If you've done broadband speed tests in the past, perhaps you should try one again and see if there's a difference?

I restarted the program and the map showed up as normal.

In the over two years I have been in SL I have made the cable guy come out more than once, made him replace some cabling he said was good, , traded cable modems twice so that I am on the third one, all of which showed no errors, used three different computers with different motherboards and operating systems.

None of this ever makes any difference. No packet loss problem that shows up in tests that correlate with SL problems, plenty of bandwidth.

I have run trace programs, tracert or whatever it is , winmtr or whatever that one's name is, done ping tests and all sorts of stuff over the course of my time here, and there doesn't seem to be a hardware problem.

Roadrunner will not lift a finger for anything associated with UDP.

I haven't tried killing the neighbors and severing their cable connections yet but I will try that tonight and report back if I dont' get caught. Thanks for the tip. (I hope they have broadband in prison.)

Would I need to take out everyone else that uses the local roadrunner service to make sure they aren't hogging my bandwidth, or would just eliminating everyone else in the local metropolitan area be sufficient for a prelimary test?

I don't think it's bandwidth issues. I can enter an area, and download data (according to the stats option) at over 900k. Some areas the textures can still take a long time to download.

Try enabling stats and see what speeds you're reaching.

Also, I'll randomly get really high packet loss. I'm not sure if their packet loss detection is working or not - because it shouldn't be getting any loss. I don't see these issues on any other system/service.

Seems like it is a problem not with our bandwidth (I hope not, since I often get 550KB/s downloads), nor with Linden Labs bandwidth, but internal communications. Probably due to all the extra continental and private sims. When we request a texture that request has to go to the server we're connected to, the server has to request that texture from the database, the database has to search for the texture, send it back to the server, and from there back to us. Depending on the methods of load balancing it may not scale up very well.

A select on the texture id from a database, even with many millions of records should be quick (assuming the index is setup properly). Latency of even a few seconds wouldn't be too bad, but we're seeing stuff crawl at times. From what Linden's have been saying, it looks like there's code logic errors that are manifesting themselves in this way.

The Map land textures are a different situation from the textures in the world generally , or at least they ought to be.

The map is only updated every so often; the entire set of textures for the entire map could be stored locally and updated only when the map is regenerated.

The data for the icons and people are the only parts that need to be streamed.
