Faster Prints

I use slic3r (if theres something better for exporting gcode for pronterface, Let me know!) and I am interested in creating faster prints.

I have increased the speed for perimeters to 80/s, infill speed to 120/s, and increased the layer height to .35 (from .25).

I'm also going to attempt infilling only ever 3 layers, rather then every single one.

ANy other methods more creating faster prints that doesnt reduce quality too much?

Depending on the strength of the part needed I have decreased Infill percentage to as low at 20%.
Rectilinear seems to print faster than honeycomb.

for many prints you can have a hollow shell. make outside perimeter 3, and infill 0. this will drastically decrease print time. for objects that are flat on top, cura has a feature to allow the top to infill and bridge properly.
