The default Inkscape SVG file size is quite big, so we would want to save a web optimized version for production.
You can use
File -> Save a Copy, then in
Save as type -> Optimized SVG (*.svg). There are some extra configuration for you to tinker with as well.
Inkscape SVG is 5.47KB, while the
Optimized SVG is 1.91KB (65% size saving)
Optimized with svgo is 1.24KB (77% size saving)
