A Question on your calculation of Office space overhead, Did you factor in the Server Locations in at least two other cities? I didn’t notice that, and there are also utilities Costs Outside rent, and those basics provided by the Building management. If those expenses are factored in then it would Appear on the Surface that LL has actually been operating at a loss for some time. A Condition i doubt would carry on more than a Few months before the various financial Trade papers “outed” their insolvency. I think, Not being privy to everything that Goes on at LL you have probably Miscalculated somewhere.

“Every time mainland property changes hands, an entire month’s tier on that property is charged” No, every time a new tier level is triggered, the difference between that tier and the previous one is charged on top of what that Resident is normally paying.

Mercia

Today US$1.061.271 was spent in 2ndL. For the sake of
simplisity, lets assume this equals the ammount users
daily feed into the echonomy.

Using todays exchange rates, this would buy the punters
L$265.824.616, which in turn sells for US$860.883.

From what I can see most of the transaction fees are
passed on to the punters (US$0.30 when buying L$ and
3.5% when selling), so my guess would be that Linden
actually sees most of that US$200k/day.

Hardly something to be ignored.

Arthur, I agree that bandwidth is one of the most underestimated sources of lag. As people start hosting their OpenSims at their homes, and suddenly figure out that at most 2-3 friends can log in through their ADSL/cable connection, people will realise how important “massive bandwidth” really is. An average of “100 Kbps per user” is not much, specially when that means that during peak hours you might not have much more than that available per user! Loading *several hundreds of megabytes* of textures on a crowded sim that barely struggles to give you those 100 Kbps will definitely lag things a lot — but that’s because the sim is doing *both* things, texture streaming AND figuring out avatar/prim position, all through the *same* channel. A more interesting design would be to separate assets from position tracking — a good reason why all static-content MMORPGs are WAY faster than SL, they can easily handle 7k avatars/CPU if they only have to deal with position tracking. So, yes, bandwidth is an issue, and having servers with dual purposes (asset serving and position tracking) will compete for the same bandwidth — instead of getting position tracking and seeing avatars/prims move, your computer is being bombarded with textures and sounds and animations and painfully waiting for the next bits and bytes that tell where people are moving or what they’re saying in chat…

Hiro, Lewis spotted the pun first

And Prokofy, I agree — I haven’t figured out not only the taxes, but also missing the additional running costs like travel, etc. For instance, how much does Lewis PR cost? Or their (external) lawyers? What about accounting costs? Put that all into the “cost” section, and things look grim. Alas, the “taxes” issue is a tricky one: are you taxed on revenues or profit in California? If they’re only taked on profit, they might deliberately show themselves as an almost-non-profit-company by increasing their expenses (that’s a very typical trick in my country, where you’re only taxed on profits and keep a running account with the IRS on value-added tax — a good accountant will always have the company very close to be as low profit as possible, and spend as much in services as providing them, thus having the VAT accounting also as close to zero as legally possible).

Sue, great idea )

You forgot taxes! Also travel.

My concept of LL as a non-profit organization:

Binary. duh.

Additionally if they are routing significant portions of their traffic, they will see a slow down as routing is not as efficient as switching, causing bottle necks.

They said recently they have a VPN connection between the data centers, this is an additional source of lag and over head. VPN means encryption, decription, larger packets. Most companies requiring dedicated bandwidth, and performance would look to technologies like MPLS, ATM, and direct fiber between colocation facilities.

Every time mainland property changes hands, an entire month’s tier on that property is charged; the monthly tier can be realized by LL several times in a month.
