Millions of files per directory, may well be a mistake... BUT there are some very smart use cases that might take advantage of GPFS having good performance with large directories -- because GPFS uses extensible hashing -- it is better to store millions of files in a single GPFS directory than artificially scatter them among directories based on the mistaken notion that large directories are bad. (Yeah, they are in most implementations, but not in GPFS.) -------------- next part -------------- An HTML attachment was scrubbed...
