[Opensim-dev] Synchronous or Asynchronous? osSetDynamicTextureURLBlendFace

[Leal Duarte]

Hi,

     On Wiki Delay refers only to extra time penalty of some LSL functions

    "... to appear immediately" yeah.. miracles...

     http request must be async, or the entire script engine with just 
stall awaiting for it...

    This http request will be far from fast, depending on network 
conditions and image size.  Also having several to same endpoint, they 
will be serielized ( ie only one after the other )  by the low level or 
even the endpoint service. Google machines are not there to be flooded 
by just you..

     Processing uses a lot of CPU. The image must be converted from 
original formal (like jpg) to JPEG2000 (using CPU only) and viewer 
texture asset format.

     When all that is done, viewers need to be told and then get the 
texture..  add several more ms if not seconds..

     Far Far from "... to appear immediately" in fact you may just 
freeze the entire region with a few requests...

Ubit.
