solrac..hola and welcome to bryce and the mad and fun forum. Don't worry about how good your English is..it is really good, btw.. we're all here to help. 

Exactly what thebryster says...don't use large textures.. or high resolution textures.

As for faster renders... apart from praying, don't use glass, water, complex scenes, high res and large textures, lights, reflections, refractions, etc..etc..etc. In other words.. the simplier the scene..the faster your renders

On the other hand.. . enjoy the ride bryce gives you..there are always loopholes to make it go a wee bit faster.. 

happy brycing..cheers
