Testing whether fcrepo4 ingest performance is impacted when more than ten thousand objects are stored with a lack of hierarchy.
The tests were run on an EC2 m3.medium instance. Tests were run with the pre-configured Infinispan configurations available in the fcrepo4/fcrepo-configs repository (e.g., file, leveldb-default, leveldb, and ram). These configurations were passed in as system properties when Fedora (via the jetty-maven-plugin) was started. Once Fedora was up, benchtool was used to ingest up to 30,000 objects and the resulting durations.log file was processed through gnuplot to generate a graph. A Bash script was written to automate this process. Ingest times across the various Infinispan configurations did not slow down as more objects were ingested. Configurations, graphs, and benchtool log output are available below.
