 Description   

The switch to Magnolia 5.5 has included a change that is making the module produce much slower backups, regardless of backup size. It would be interesting to know what caused this change, and to go back to quick backups, if possible.

Here are some figures:

  • 5.4.6 -> 50 MB, 0:05
  • 5.4.13 -> 50 MB, 0:05
  • 5.5 -> 115 MB, 1:30
  • 5.5.4 -> 115 MB, 1:30
  • 5.5.5 -> 600 MB, 1:30

An interesting test to do would be to see the difference with an actual repository of a few GBs.

Issue is probably still there, but is not going to be tackled because of the low priority.
