Don't run multiple vehicle park sims on one machine.

I have noticed that sim transitions in the vehicle park have been unusually rough lately, viz. tumbling in precise circles for ten seconds and then snapping into place, getting dumped out of vehicles (which irreversibly destroys their sit targets and requires a relog, by the way), et cetera. Today I figured out why. Sim CPU is 0.25 or 0.33 in most of these sims, indicating that several of them are sharing machines.

The vehicle park is supposed to be the best place in SL to develop and use vehicles. As it stands today, crossing from one vehicle sim to another at low speed is more of a crapshoot than traversing 20 or 30 fully built-up sims at high speed. I am not exaggerating, it's that bad.

I concur with Huns,

I've noticed this too, and generally have nowhere reasonable to test vehicle scripts these days

plus, considering all the wonderful thank you very much water sims we have now, i'd be inclined to raise the six original "vehicle" sims and plaster roads all over them. it'll be much easier to find the dog fit remains that way.

hey, this could be a great use of some'f the 2.26'ers.. since they're rarely crowded and generally have very low script counts the vehicle sims could run one per older sim no problem and it'd really help transitions compared to multiples on the same machine (since they'd all have more memory and faster response times)

Sounds more like the hand-off code for multiple-regions-on-one-CPU needs work. If that was cleaned up, running multiple vehicle sims on one machine shouldn't be a problem.

I concur more with Tiger's post than with the idea of dedicating one of the newest servers to the vehicles sims - or even with running a single vehicle sim on a single server.

While I would prefer the best possible flight response, I don't think that the servers are the problem here - instead it's the handoffs. I don't crash when I am flying alone in the sims or even when the fps is below 100 if I do not attempt border crossings. Border crossings are the bane of flyers, in my opinion, not single servers vs multiple servers or even the slow versus the fast servers.

Fix the handoff issue and then I could agree to rethink my user-perspective stance that dedicating the fastest/single server setups to the vehicle sims is not a reasonable allocation of resources.

On the topic of boarder crossings, has anyone noticed that there are places where the roadway crosses through sim corners? That being where the road is in 4 sims? I believe if memory serves me there are 4 of these such places. If LL knows that sim crossings are the bane of vehicals why do they put roads on 4 way crossings?

Sometimes when I fly through sims that are sharing a single CPU I notice some control lag, so it is more than border crossing that makes this configuration undesirable.

Multiple sims on one CPU is a great idea for void sims, since they are primarily for travelling from one place to another. Until the sim code is greatly improved, or CPUs are much faster, I don't think it is a good idea to run the vehicle sims like this.

Putting the vehicle sims on a dual Opteron box might be a very good idea -- since communications between the virtual machines wouldn't need to go through a real network, sim crossings could be much smoother than normal. Dual Opterons should be able to handle the load.
