[Opensim-users] Assets 101

Fri May 1 20:45:14 UTC 2009

Hi
As suggested in the mail thread, I tidied up the code for this feature and
added it to the forge

http://forge.opensimulator.org/gf/project/uploadext.

- I haven't been back to it since Feb though, so will probably need some
tweaks to get it to work against current trunk.

Main problem with this approach is the speed of the upload / download.
Whilst OK for terrain files, it is _painfully_ slow for larger things like
oar files, my Osgrid region took around 30 mins to transfer through
this mechanism- SCP takes around 30 seconds.
