Christoph Kutzinski - [26/Sep/05 06:52 AM ] This is the patched AbstractDiskPersistenceListener based on OSCache 2.1.1 There are 3 main changes: - don't delete cache files before storing (not necessary IMHO since the file will be overwritten by the outputstream anyway) - used buffered in and output streams This gave me a performance gain of ca. 20% for removing 750 entries with each around 3 groups - don't serialize groups, but write them as plain strings This gave me another 20% Caveat: the last change isn't compatible with group files written by old versions.

Lars Torunski - [26/Sep/05 05:10 PM ] I merged your changes in the 2.1.1 release file with the bug fix CACHE-189 of the 2.2 rc release. Please check if the merges are correct in AbstractDiskPersistenceListener.java.patch_2.2-rc file.

Christoph Kutzinski - [27/Sep/05 02:46 AM ] The patch looks good to me. (I wanted to report one minor issue, since I thought that the fout.close() call in store() is redundant. But I just realised that the ObjectInputStream constructor can throw an exception, so it isn't)

Lars Torunski - [12/Nov/05 03:38 AM ] Using buffered in and output streams to increase persisting performance about 20%. Groups are still serialized for backward reasons.
