Alpha-1 Test Results

The most recent Alpha-1 benchmark test results I see are from June 2013:

These tests ingested a very small number of objects/containers (10), and files ranging from 1 byte to 100MB.

Alpha-3 Test

...

  • Number of Objects: In some initial testing on my laptop, I noticed degraded ingest performance as the repository size grew, particularly after 20K objects.
  • Datastream Size: In my experience, the larger files in those tests (1MB, 8MB, 100MB) are fairly typical for high-res images and audio/video derivatives, and audio/video masters are much larger.

Testing full-scale ingest would take more disk space and time than we have available.  So it probably makes more sense to do two separate tests:

  • Many Objects: 25K objects with small datastreams (100KB): 2.5GB total data size
  • Large Datastreams: 100 objects with larger datastreams (50MB): 5GB total data size

In addition to varying the number of objects and datastream size, it is particularly important to perform some tests on the same hardware in order to have directly-comparable data:

  • Thread Test: Run the same test on the same hardware with increasing numbers of client threads
  • Fedora 3/4 Comparison: Run the same tests on the same hardware with both Fedora 3 and 4

Using Benchtool

The ingest benchmarking tool is available on github: https://github.com/futures/benchtool

To build and run benchtool against Fedora 4 (creating 1000 objects with 1KB datastreams using 5 client threads):

Code Block
git clone git@github.com:futures/benchtool.git
cd benchtool
mvn install
java -cp target/bench-tool-0.0.1-SNAPSHOT-jar-with-dependencies.jar org.fcrepo.bench.BenchToolFC4 http://localhost:8080 1000 1024 5 ingest

To run against Fedora 3 (creating 1000 objects with 1KB datastreams):

Code Block
java -cp target/bench-tool-0.0.1-SNAPSHOT-jar-with-dependencies.jar org.fcrepo.bench.BenchToolFC3 http://localhost:8983/fedora fedoraAdmin fedoraAdmin 1000 1024 ingest

While running benchtool will output a running progress percentage, and then output the time to perform the ingest:

Code Block
Complete ingest of 1000 files took 23301 ms

Results

The Alpha-3 benchmark test results from December 2013:

Create/Read/Update/Delete Test Results

Testing was performed to create, read, update and delete objects/containers in Fedora 3, Fedora 4-alpha3, and Fedora 4-alpha5 (4-current), using the cURL command-line tool (Fedora 3 test script, Fedora 4 test script).  Each test run processed 3,000 objects/containers, and each object had a single 10MB binary.  Each repository was tested twice and the average times are summarized below.
