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>

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

<p style="margin-bottom: 12pt;">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>
