It would be interesting to see how it worked with real people behind the avs. Maybe you could be asked to try and get a bunch of volunteers together through your blog - I imagine it would be popular.

Arcadia Codesmith

I imagine real people would be less taxing than a well-designed loadbot.

And if that's the case, this could be a fundamental shift in the compartmentalization of OpenSim worlds (and Second Life, if they grasp the opportunity).

It's a hard sell to get name acts to perform live for an audience of forty. But if you can deliver 400, 4000, or more? Game changer, right there.

If only they had 100s of avatars.

Nine Warrhol

Was this a 'real world' test? lol I'd like to know how many of those avs were wearing a zillion scripts and how many had on blinging parts? :p

It's a cool achievement jokes aside.

Ann Otoole InSL

an impressive achievement. hundreds of simulated bots in a seemingly single simulator all without any client scripts or customizations.

Someone else already did it.

Dave Bell

It's possible that this needs a lot more hardware for the region than is usual. Which suggests it isn't going to be commonplace. But some of the event venues could be set up to run on such a system.

Arcadia Codesmith

It suggests to me that perhaps there needs to be a floating pool of server resources, not dedicated to any single sim but available on demand to support population surges in any sim. I'm assuming the scene partitioning in the diagram happens dynamically.

Ron Overdrive

I remember when Hurliman came to us on #Imprudence to help with this test and some of us were there for the stress test (not the tech demo). It does a pretty good job, but yes the bots really needed active scripts to simulate more real world tests. Considering they're marketing it as 500+ instead of 1000+ like they achieved during the stress tests is probably Hurliman being conservative with the numbers to factor in attachments.

Chenin Anabuki

This is highly commendable effort for pushing the capacity limits of an OpenSim region. It will certainly have significant impacts on the applications we are building for simulations and training in-world. We look forward to the day it becomes absorbed in the OpenSim released binaries. In the meantime, if you need live human beings to help test load the upper limits of concurrency, just holler at Avatrian.

ZenRascal Mandelbrot

I like what Arcadia seems to be getting at, dynamic shifting of resources as needs develop. (I tried to express something like this in a comment to Dream Projects recently - tinyurl.com/2ddbfdb) The bird's eye view is scalability applied to (1) avatars and (2) regions. Currently in SL, regions that are tied to a fixed hunk of server farm hardware (one CPU core) and avatars to the (single) user's computer. This design rigidity will never escape the bonds of the limitations we're used to (3-4 dozen avs per region max). And as a populated region gets laggy, most of LL's server farm cores are idling with 0 or 1 or 2 avs to deal with.
