The cost of decompression is something I've run into, regarding 3D data. Draco, which is a highly efficient compression system for 3D mesh data, is primarily used with browser based webGL / gltf model rendering, and it achieves excellent compression ratios for online transmission. However, the decompression cost at the viewer's end often means that you will wait longer to see your 3D model than if you had used a simpler format, especially over fast links.
