Fedora 4 can handle a large number of objects, but performance degrades if there are too many children and/or grandchildren of a single node.
Federated filesystem
Files in a single directory
Files in a hierarchy
Using a three-level hierarchy (256 top-level nodes, 256 second-level nodes in each, 256 third-level nodes in each, and one 10KB datastream in each), performance retrieving files and listing the second-level nodes did not degrade with larger numbers of objects. However, listing the top-level of the repository ("toplist" in the chart below) degraded roughly linearly as more objects were added, and became increasing erratic.
