If you have access to the Top Scripts data in the Estate/Region menu,
take a look sometime to see where the heaviest demand is. Every time I
do that, a handful of individual avatars are at the top of the list
(my own included .. :P ). We carry a lot of script loading when we
have Mystitool, AOs, and a couple of proprietory HUDs going at once
--- to say nothing of (ugh!) scripted hair and shoes. In most sims,
script time is not the major factor determining lag, but if your sim
is already heavy on the use of textures and you have a gathering crowd
wearing loads of prims, those personal scripts can push stats over the
top. That's why some of the big shopping areas in SL display a popup
dialog as you arrive, asking you to disconnect AOs or put scripts like
Mystitool into sleep mode.
A sim that has even a few physical objects putting a strain on the
physics engine can also hurt. I was talking with a sim manager last
week about horrific lag on her sim when she pointed out that they had
two glowing "comets" moving through the sky. Each was a massive
physical object that took immense server resources to control. Avs who
drive vehicles into the sim may have the same effect under some
circumstances.
You might also look at View >> Statistics Bar. As Time Dilation drops
further and further below 1.00, lag increases dramatically. Same
thing as FPS (frames per second) drop much below about 40 or script
time gets over about 20 ms. If you are approaching those limits, it
doesn't take many new avatars on the sim to slow things down. Again,
you can do many things as a sim manager to keep the background load
under control, but much of what you see in those statistics comes in
with your visitors.
Having said all of that, the lag that any individual experiences is
still often a measure of their client's efficiency or their Internet
connection. Two avs in the same sim can see radically different rez
lag if one of them is on a slow DSL connection and the other is on
optical cable, or if they have very different amounts of memory on
their graphics cards. On the rare occasions when I try to log on from
my aging laptop, for example, my own FPS is so low that SL looks like
a 1920s silent movie -- uncontrollably jerky. When I am working with
newcomers at the reference desk on Info International, I occasionally
hear comments about lag even though the sim stats are fine and I am
seeing no problems myself on my nice desktop. It usually turns out
that the newbie is working with a substandard machine or on a weak
wireless connection.
