[Opensim-users] Memory usage

Very interesting. My setup is quite different in that I do not run the grid
but rather use the OSgrid. I only run the regions. That could be a huge
difference. However since OSgrid is officially designated as the "opensim"
test grid, I would hope the developers are serious about the results people
are having who use that grid.
I am in the process of trying to discover exactly when this problem started
for me as was earlier requested.
The different versions I can test with are these releases from OSgrid:
osgrid-opensim-01162015.v0.8.1.97ac80d
osgrid-opensim-01172015.v0.8.1.1f04e1b
osgrid-opensim-02212015.v0.8.1.7b9ad11
osgrid-opensim-03142015.v0.8.1.8b13e4e
osgrid-opensim-03172015.v0.8.2.83e58eb
osgrid-opensim-04052015.v0.8.2.8d66284
osgrid-opensim-04122015.v0.8.2.d96d31b
osgrid-opensim-05072015.v0.8.2.c74cef0
osgrid-opensim-05092015.v0.8.2.adf0f49
osgrid-opensim-05232015.v0.8.2.abb3bb6
Later today I will cycle all of these releases on one of my regions and run
a test using "monit" with my original parameters set to see which version it
was that started using so much simulator memory. The change control on my
home network is not near as professional as what I lived with at IBM for 31
years. Now I depend on my own memory. That is not a very good choice in my
case. Luisillo's testing was far more accurate with excellent metrics to
compare. Bravo.

I have not problems or issues with memory.
My memory test results:

All users in this test are using Radegast. All have Inventory with
1200 Items aprox.
and worn scripts as AO, radar and resizers in hair and shoes.
