No, because I was not aware of that option. With ScriptDelayFactor = 0.0, the LSL version changes from an average of 2.15s to 2.10s. No big deal. The C# version is still around 0.2s. I switched to C# because i noticed my script spent most of its time into list handling (llList2Rot, which was a first speed gain over 4*llList2Float). Since LSL has no array structure, we use lists to emulate them and waste a lot of time here. Then, replacing llPow with System.Math.Pow gave me another speed boost. Finally, replacing osSetPenColour, osDrawLine with direct drawlist manipuations (drawList += ) accounted for the overall 10x speed increase. Of course, that depends a lot on your application. If you are manipulating prims, the gain may be near zero. If you do a lot of math and matrixes, it may be higher. _______________________________________________ Opensim-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/opensim-users
