[Opensim-users] MySQL on seperate server?

Tue Feb 16 20:14:05 UTC 2010

here is an example of what happened to me on a few Grids I have tested. Per
AV I am uploading / downloading roughly 40KBytes a second. Not kBits. That
is full load with everything going on. So I am giving the most I have seen
in this case. That is roughly 320 KBit upload and download just for one
avatar. So in theory, you should be able to push less then 40K IF your
avatars are not really doing all of what they want them to. Example : Voice.

So with a 1 Meg upload, your looking at around 3 Avatars smoothly. If your
going to go with 2 Meg Upload which some of us have, then your could go to
about 7 Avatars smoothly. Again, this is all dependant on what your USERS
are doing. If all are building and in Voice all at once, then 1 Meg = 3
Avatars smoothly.

Keep in mind, this is a test I did myself on 5 Grids I have tested. Each
with different ISPs. So if your going to run a Grid you also have to account
that the region that ties into your main region ALSO has to accomodate for
the extra communication between each region that is not on the same computer
/ ISP. AND they are constantly 24 / 7 communicating. So if you have a
bandwidth limit, you could be in trouble. At a Previous version of Sim
world, we had 500 Megabytes transfer for about a weeks worth of time. And
that is with only 8 regions and VERY little activity. The limit ?  1
Terribyte. So in one week, we ate up half our bandwidth limit. ( Thats all
the HOST allowed at the time )

Bottom line, you MUST do the math to see if this is even possible to keep
running before spending a lot of money.
