possible under current architecture, not disputing that. I do have to wonder
what people consider as being an event suitable for 1000 people in a single
region – that’s a lot of people in not a lot of space (though thinking in three
dimensions might help), but what do you gain from such an event? Chat alone
would be almost overwhelming, and with 95% of attendees not knowing how to pan
the camera most of them would see nothing but the head of the person infront of
them – so I guess if you want to emulate real life, you got it.<o:p></o:p></span></p>

the absence of 1000 friends to test a simultaneous login, we all have to
improvise, so if it’s a case of loading up as many avatars as possible with all
clothing layers made with high-res textures, wearing a thousand prims each,
etc. then yes, it’s not an entirely unreasonable scale test.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-bottom:12.0pt'>well i think your sorta missing
the point, say i did reduce my avatar login footprint by 10, that would only
mean that if 10 people simulatanously logged in, which if your talking about
1000 avatars at once is going to happen, it means that you will get the same
results if 10 avatars hit at once, so honestly even if we reduce the footprint
by 90% we still have the same problem on logins, the biggest problem i see is
mass login, when your talking about getting 1000 avatars into a region for a
single event, especially if it crashes you could be potentially looking at over
100 avatars trying to log in at the same time, how do we handle this?? if
your talking about 1000 avatars you need to talk about exteme usage case, not
just fractional usage.<br>

event and the design of the sim itself. Build a sim with many thousands of
highly textured prims and complex scripts and you might as well just cut down
your ram, step down your processor, and accept defeat. Code optimisation is
nothing without a little care and attention on the part of the sim designer to
make the experience as smooth as possible for attendees.</span><o:p></o:p></p>

<p style='margin-bottom:12.0pt'>Minor mistake in my last posting, it should
have read (8000 variously texture prims in the ballpark of about 500+ texures
or so).<br>
<br>
and since i am recommenting again, i think its important that when we talk
about 1000 users, we are not talking about 1000 ruths with zero inventory and
not chatting and doing real world things, pcampbot is a horrible representaion
of 1000 like i said before every 1000 pcampbots is probably not even equal to
20 real world avatars actually doing something with the simulator.<br>

<p>the only bad thing about bringing up the Pcampbot login test was at the time
pcampbot was not pulling assets down from the scene locally to itself, so
realisticly those 1000 pcampbots were probably generating about the same amount
of login traffic that about 10-20 avatars would have been likely. The
only real solution to this problem will likely be load balancing and many
servers working together to break the 100 avatar limit, the chances that 1
server will be serving 1000 avatars is completely impossible, i honestly dont
think we can ever optimize it enough for even the fastest servers to deal in
1000 avatars, though i do hope we can atleast get to around 100 or more.
One test I have done recently that throws a monkey wrench into my thinking
about this, my Region (OKC) Ka which is about 12000 prims and running just over
1000 scripts, when trying to log into the region with just 1 avatar that is
wearing a 1700 prim avatar that uses every single attach point, i am 100%
unable to log into the sim ever. One other thing to note is that my
avatar has between 11k-12k inventory items and basiclly trying to access any
simulator with more than about 1000 variously textured prims in the ballpark of
about 500+ textures or so (even afer running the predecode-j2k) i am unable to
log in at all. So again if 1 avatar cant access the sim, i personallly
dont see 1000 avatars entering a simulator anytime soon if at all ever,
atleast like I said in the 1 server world, this is probably going to require
some major hardware/pipes to achieve.<br>
