Question on how to prevent lag

Hello forum,
I am renting an apartment in a sim which had lag issues, so the sim owner debugged it, and found that one of my items was very laggy, so they returned it.
I know there is a measure called avatar rendering cost, and that one wants to keep this low if one wants to attend a crowded sim, but I have not really found a similar accurate way to measure "object rendering cost", there just seems to be general rules of thumb like how large is the used texture, and are there bad scripts in the object. But when one has bought a non-editable item, it is hard to determine how laggy the item really is by these parameters. Also, I have other scripted objects in the sim which were not lagging, and none of my items including the laggy one seem to have bad scripts, as there were no error messages. I have searched for, if an "object rendering cost" or similar measure exists, but I have not found anything except the general rules about bad scripts, texture size, etc. on it.

So I wonder: Is there a more accurate way to determine, how laggy an item will be in a sim? And if yes, how do I measure an items potential for laggyness?

The above blog has a great post about lag. Is the sim a Homestead and are there always lots of avatars there?

Hi Sinitta,

You can find out the equivalent of avatar rendering costs for any object by "wearing" it, just like an attachment - find it in your inventory, right click, attach to ... (wherever). Don't worry too much about ARC though, lots of people who seem to know what they are talking about say that it has little to do with what actually causes lag. There's a good article called The Anatomy of Lag or something. Some kind person will probably provide a link shortly.

If the object was returned to you as being very laggy it probably used a lot of script time (I think I got that right). Estate managers have access to tools for determining which scripts are using most resources, but tenants and mainland land owners must rely on guesswork (there's a jira about it somewhere). There is a way you can determine script time for an individual script if you know lsl and the script is moddable, but I don't know enough to be able to tell you how.

Beyond that, it really is just rule-of-thumb. Things to avoid seem to be scripts that have timers or sensors on a very short cycle, lots of big textures, lots of sculpties etc., but it looks like you've already looked at this.

I see Thank you, Argus and Spinster, good article. Yes, I should find the JIRA and vote for it.

ps: I have no idea, if it is a Homestead place. It is a roleplaying sim with residential rentals and sceneric builds. I have not seen any sims being very full, but there are always people and bots there. The bots are run by the sim owners.
