Arnold has the "maketx" commandline utility to make .tx files out of textures. At work we made a batch job for the farm that converts a scene's textures to (mipmapped) .tx for Arnold's sake.
In the renderer options somewhere there is a toggle to make Arnold use .tx files if it finds them in the same root as the texture paths. It's pretty handy.
