Storage Characteristics

As any other db4o operation delete is dependent on the performance of a storage location. This can be easily compared with a database stored on a hard drive and in RAM:

Delete test: RAM disk

Store 90000 objects: 5973ms

Deleting 1 object of depth 3 on a RAM drive:

Deleted all objects: 5249ms

Delete test: hard drive

Store 90000 objects: 5043ms

Deleting 1 object of depth 3 on a hard drive:

Deleted all objects: 7475ms

The general rule is: the faster the drive is the better is the performance.
