It might just be network lag. When you log in for the first time, the
amount of data that needs to be sent to your viewer is substantial. (The
whole environment, your appearance and your whole inventory need to be
cached.) Once all that data got transferred, things are usually moving
much smoother. I'd open up the statistics window (ctrl+shift+1) and keep
an eye on the bandwidth.

Hey there,
thanks for all these enlightening responses. I have one more related
question. When I was trying out kitely, a few minutes after logging
in, I could find that things were unusually very slow (am always
comparing with am used to that Linden Lab servers). Rezzing a simple
cube would take longer than usual. Then after some time, response on
kitely improved somewhat. Now am thinking, may be because resource
allocation on amazon cloud is somewhat dynamic, could it be that it
takes a while for all necessary resources to be allocated ... (I
haven't absolutely no clue about how all this happens in the
background, this is all speculation from someone who has a lot to
learn). Let me know your thoughts.
Thanks

I haven't run "lots of scripts" on OpenSim, but I would certainly agree
with Marcel: running two copies of the SL Viewer, one connected to SL,
one to your laptop-hosted OpenSim, AND the standalone OpenSim on the
same laptop is being too optimistic :) Just one of the viewers will
take so much CPU (even though I believe the SL Viewer(s) don't use
multiple CPUs...) that it will starve out the poor OpenSim application
(and the database!) trying desperately to run with whatever CPU cycles
are left.
As a comparison — and, again, I'm not running many scripts really — I
have tried to run the same installation of OpenSim on a desktop iMac
from early 2007 and a Pentium IV-based "server" (from around late 2008)
which is only running Linux with OpenSim, MySQL, and nothing else
besides. In both cases, all I have is two cores and 2 GBytes of RAM.
But while the server has nothing else to worry about — no GUI — the
iMac obviously has the whole of Apple's GUI stack running
The iMac barely handles a single region on OpenSim, even if I run the
SL viewer from a different computer. The Linux box handles a
10-sim-minigrid without sweating. While everything on the iMac seems
sluggish (but it certainly works!), there is little difference between
regions hosted on the Linux box and Second Life, for a very low number
of logged-in avatars. Perhaps the good thing about OpenSim is that
hosting many regions with few avatars and few scripts will not make a
huge difference at all: in theory, you could host hundreds of regions,
assuming that you're just using one or two at the time :)
So I don't think that running so many things on a single laptop will
give you reasonable performance on OpenSim, and the "competition" is
unfair: the laptop is doing a ton of things already, and has few
resources left for OpenSim. Specially if you're already running two
instances of the SL Viewer on it...
On the other hand, I suppose that having a high-end, eight-core laptop
with 8 GB of RAM and a dedicated graphics card might not create such an
impact on OpenSim performance :)

A laptop cannot compete with those ...
