[Gramps-devel] Compression rate on compressed .gramps ...

[jerome <rom...@ya...>]

Hi,


On this end of year I find something interesting by backporting a improvement made by Doug some months ago on trunk.

http://gramps.svn.sourceforge.net/viewvc/gramps/trunk/src/plugins/export/ExportXml.py?view=patch&r1=18238&r2=18272&pathrev=18272

I was cleaning my data, I made backups and patched the 'non-idempotent XML handling' on XML export for current stable release... It was for my own use and for testing data migration or diffs between backups.

After using the patched version, I thought that I made a mistake...

unpatched data.gramps : 870Kio 
patched data.gramps : 751Kio

Fortunately, it is not related to the content: my data; but the compression rate/ratio !!! I do not know what is the unit but:

unpatched data.gz : 5.79
pachted data.gz : 6.70

Conclusion: to sort handles seems to also generate a gain on file size!
:)


Happy new year!
