Thanks for the info. In summary, to speed up ls color induced processing significantly, disable stat() and getxattr() calls with: LS_COLORS='ex=00:su=00:sg=00:ca=00:' A general point though is that colors are for human processing, and how fast can one process the output from ls :) I.E. if ls is being written to pipe/file or somewhere where speed may be important, the coloring is disabled by default anyway. cheers, Pádraig
