Hi, I'm wondering, has this to do with the disabled stat-prefetch translator? I have a unify over 2 afr (2 bricks each) volume, spanning 2 servers that afr each other. A "du -sh somedir" takes no time on each server directly (one has 82 MB, the other 84 MB in somedir, coming from ~10.500 files files on each server (in a heavy neseted directory structure). If I do a "du -sh subdir" on the client, it takes like some minutes until the 166 MB result is ready. Test is done on latest tla checkout. Thanks, Sascha
