Why are svg files not made smaller using scour?

[神癒礁湖 (Rafael Laguna)]

I apppreciate a lot your info. I'll take a look into that python script.
But I will continue using the Inkscape batch one. I prefer treating the
icons as Inkscape SVGs, not as standard SVG, because some gradients and
clipping masks are a bit more complex than XML/SVG standard definitions.

In a folder I've recently "compressed" the real gain was about 40%, pretty
similar to Scour.

Thanks so much for your apport ;)
