concurrency will be affected by your underlying filesystem as well. which filesystem you got? In our environment we have ext4 and xfs. ext4 is a touch faster, but doesn't handle as much concurrency, while xfs handles lots of streams fairly well, but runs slower. However, aside from that don't expect much from me ;) -greg -------------- next part -------------- An HTML attachment was scrubbed...
