With the release of the Havok 2012.1 update and Pathfinding came an increase in bandwidth used. In the articles #SL News Week 33 and #SL News Update Week 33 I mention the problem. See JIRA: SVC-8124 – Excessive “ParcelOverlay reliable” messages sent by regions since last rolling restart (2012-08-08). Votes=124 – Watches=90 – 8/24. Resident interest in the JIRA shows it obviously not a big issue, unless you have a bandwidth capped/metered Internet service.
The fix for SVC-8124 was added to all 3 release channels to increase the probability that it can roll to the main grid next Tuesday.
I asked Oskar Linden if the Lab has seen an increase in bandwidth used since the PF release and 8124. He says not that he has heard. I suppose that means either it is a small enough problem, for the Lab, that they aren’t talking about it in house or Oskar has had his head down working and not noticed it.
Posts from the JIRA suggest that it makes no difference whether Pathfinding is enabled or not.
Island regions without a diagonal region to the SW do not suffer the problem.
Those testing the problem in the RC regions are seeing considerable improvement or no problem. So, it seems the problem is fixed.
I am surprised that people with capped or metered services don’t monitor their Internet use. Asking some old people about the good o’days of dialup, they remember watching the clock to keep their phone bills down. That seems reasonable to me and makes me wonder what has changed in this generation.
I’m already jaded enough to not trust any company with a blank check. I believe anyone billing me for hours or quantified services is going to be tempted to pad the bill. So, I keep track of what I’m using.
In Week 33’s update I listed a couple of Network Monitors. I’ve been using NetWorx’s monitor to monitor my use.
I’ve also been watching the use graphs as I fly around the grid. I have been to regions where my bandwidth use is high and stays there. But, I have not been able to duplicate the problem in the majority of regions I visited.
My home is on the very south edge of the region. I’m just east of center. The simulator version is Second Life 3.3.4 (262321) Jul 24 2012 04:02:05 (Second Life Release). My average BW in the area is 15 to 45 kbps. Even standing in the SW corner looking south and southwest it doesn’t change. So, from my perspective the problem has not been pervasive.
It helps that the region to the south of me is basically empty. I can TP from the south region into my home and hang the BW at about 600kbps. It will stay high until I start walking around then drop back to 15-45 kbps.
I find that Networx’s measurements and the viewer’s Viewer Statistics panel do not give me the same readings. When my Viewer Stats are showing bandwidth (BW) in the 600k/sec rate Networx is showing about 100k/sec.
The amount of difference varies, but Networx is always less by a significant amount, about 1/6th. When I asked Oskar about the difference he was not sure what it is the Viewer Stats BW is actually measuring.
The problem is getting resolved and the Lab has rushed the fix through QA, as much as possible, to get it out. In week 35 we should see the problem resolve.
