[Opensim-users] Slow handling of POST -

Fri Nov 2 03:36:20 UTC 2012

Hello until this problem is sorted, can someone tell me what is the
final recommendations? Uncheck http for texture and inventory in debug
menu?
I am also experiencing instances where contents of objects with other
objects taking forever to load, don't know if this is related.
