Region performance bug but only on one region

[Eon Peterson]

I have recently acquired a Homestead region which seems to work well in most respects, but there is one major problem with a scripted vehicle which works normally on all other regions I have tried it on.

The performance of my scripted vehicle (a tractor and trailer) is proving to be an excellent benchmark, or reference point, by which the performance of the sim can be evaluated.

Now that I have been on this sim longer, problems seem to be getting worse on a daily basis.
I have been noting these things - a list of which follows:

1. There seems to be a fair amount of lag, as evidenced by the slowness of blue menus to appear, or to act, or to refresh - but it doesn't do it ALL the time.

2. Back to the tractor again: the front wheels, when used on my sim, turn left and right independently of each other AND out of sync with the arrow keys on my keyboard.

3. The tractor now drives along bucking like a bucking bronco. This happens on Linden terrain as well as on a single prim road, so it has nothing to do with the surface.

(I have driven the tractor on different sims and it worked perfectly - everything was in sync and co-ordinated.)

I have contacted the vehicle creator who came and saw for himself what happens, but couldn't explain it. I contacted an Estate Manager, and both creator and EM let me use their regions to test it out, plus I have used it on my own old parcel, where it also performed perfectly well.

I asked LL Support, and they changed the server and checked all the stats and found everything was working normally. Naturally I have restarted the region several times.

I've heard it mentioned that a sim has a program inside it which runs it, and it could have a bug in it - is that possible? 

Where do I go from here? 

Thanks.

are you using any of the megaprim sim surround decorations? those can do strange things to vehicle physics since some really cover the whole region. if you want to experiment without a rebuild, try rezzing a test platform up in the sky, away from any builds, and see if that works better.

[Eon Peterson]

Thanks Obvious, I shall try that.  It had crossed my mind in fact.  I'll report back - although the Linden who looked atr the sim didn't mention it.

[Eon Peterson]

Yep!     That's exactly what was causing the issue!

But I don't think I wanted to consider it might be that because both my wife and I love the sim surround. Wouldn't you have thought that the kindly Linden who visited our sim and tested it for performance would have known that it might have been the megaprim? 

Now I've got to try and convince my wife that it's more important to get the harvest in for next winter, rather than having such a delightful surround!

Thanks again for your help Obvious.

LL have a long uncomfortable relationship with megaprims. they won't support them because the system hasn't been tuned for objects that size, but they are also reluctant to tell people to get rid of them since that generated anger back in the day, and they do allow some cool content to be made. so if we use them, we are on our own.

if the surround is modifiable, you could attempt to link it to a small regular prim, with the small prim as the root, then set the megaprim's physics type to none in the Features tab. save a backup of the surround, in case this experiment does bad things to land impact, but if it succeeds it may solve the problem. sculpty land impact is capped now, so the odds are not so bad.

[Eon Peterson]

Thanks for that again, Obvious.

No, it wasn't modifiable but I got round it by buying a quarter sze off-sim environment - and putting one of those out at each corner, which has a similar look to the original. 

So I'm in the good, and unusual, position of having my cake and eating it (being able to use my tractor AND keeping my wife happy!).
