I just thought you wanted to save internal storage and sending it all to extsdcard would do that. Once moved and on extsdcard you would be eliminating the need for pathsubstitution. The wiki states that using this method (pathsubstitution) will slow the loading of thumbnails.

FROM THE WIKI:

Code:

Note: This will slowdown thumbnail loading, but might be worth it for low-memory devices.

Thumbnails
Sharing the Thumbnails folder with Path Substitution is prone to problems, primarily because the Texture Cache consists of two interlinked data stores - the Thumbnails folder and the SQLite database Textures13.db. Sharing the SQLite Textures13.db between multiple clients is not supported under any circumstances due to the liklehood of database corruption.
Since sharing of the database is not realistically possible, attempts at sharing only the Thumbnails folder will either fail completely, or result in some artwork items never being displayed, or you may experience artwork being displayed but with higher or lower than expected image quality or even image corruption (a result of different clients overwriting previously cached artwork, as not all clients cache artwork at the same resolutions, or even use the same image formats).

If you must use Path Substitution to relocate (rather than share) your Thumbnails folder, by all means do so but only for individual clients and their associated Thumbnails folder. Do not share a single Thumbnails folder between multiple clients, as the Texture Cache is simply not designed to support this and you will experience problems.

Just a suggestion is all. I use it on an old Ugoos android box I have and see no real lag other than at start of Kodi.
