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. |
Repository storage
Objects under a single node
Under a single node, batches of 500 objects were created, each with a single 10KB datastream. After each batch, the entire directory contents were listed using the REST API ("whole"). The test was then repeated using the limit parameter to list the first 1,000 objects ("paged"). Listing the objects scales roughly linearly in both cases, but much more steeply for listing all the children. Using paging, acceptance is acceptable up to 30,000 children with no sharp increase observed.
