Hi all
I've got a script running which basically reports when dilation falls below a certain level (let's say 60%)
Now most of the time dilation is fine but a good few times a day it reports a sudden drop (to under the defined limit such as 30%)
Now the sim is private and therefore I know nobody is on the sim affecting performance and that the scripts running are "reasonable".
So what else could cause these drops ?
Thanks
Voodoo

Got exactly the same issue on a (void) sim only occupied by myself and my SL partner.
Been monitoring using Mystis cool little scripted sim tester - but it rarely finished a run without at least 2 sharp dips in dilation values for the sim.
I recently totally cleared the sim and the issue was still present - i believe a number of JIRA issues refer to this phenomenen, and some date back quite away.
Very very annoying.

I know LL is looking into a problem where people TPing into a sim causes a drop in performance. If a bunch come in at the same time, the drop could be very obvious.
Time dilation is how the physics stuff is performing versus real time. If it's at 1.0, as good as it gets, the sim is moving avatars and stuff around in pretty much real time. If time dilation drops, it means the sim is lagging behind.

Is this something that is affected by the other sims on the server?

If it's an OpenSpace, then you have your answer... it's sharing performance issues with like 3 other sims. Other than that, I think it could one of many things we know little or nothing about, like routine simstate saving

From: Osprey Therian Is this something that is affected by the other sims on the server? We know that sims on the same server host have to share stuff like disk and memory. The network port too, I think. If a sim is abusing these things, it probably can impact the other sims on the same host by starving them of those rsources. I'm not sure that that really impacts frame rate and physics frame rate, though. Those things are (I think) mostly CPU-bound so if another sim was, for example, eating all the network bandwidth of the host, it'd mean that the sims would have a slow network but not necessarily a low framerate. I'm just sorta guessing on this, though. That's for full sims - for openspace sims where you're sharing a physical processor, I'd say that another sim on the same processor could indeed cause time dilation problems. From: Day Oh If it's an OpenSpace, then you have your answer... it's sharing performance issues with like 3 other sims. Other than that, I think it could one of many things we know little or nothing about, like routine simstate saving Up to 3 other sims just on the same processor! Up to 15 other sims on the same server.. |
