Job Repository performance comparison

This is a quick performance comparison of repositories in different configurations for Ganga-4-2-0-beta1

The test program is here: CVS/ganga/python/Ganga/test/time_jobs.py

The options used:

  • registration: bulk_size=10, cnt=10, modify=0
  • registration&commit: bulk_size=10, cnt=10, modify=1

Times are in seconds. The repository is initially empty at the start of each test.

type registration time registration&commit time
Local/tmp 0.04 0.05
Local/AFS 0.19 0.21
Remote/unauthenticated 0.17 0.16
Remote/SSL 0.43 0.37

TODO Scaling behaviour test

repeat the tests by adding more jobs until 5000 jobs are there
