Hi Troels, The loading of states is rather complicated as there are many parts:
- Compression. You can turn this off for much faster saving and loading, relax already supports this. - Base XML creation and parsing. This uses standard Python libraries (xml.dom.minidom), so we have very little control over this. It might be worth looking at to see if there can be optimisations made. I have never looked into this. Understanding this library a little might help with optimising the next part. - Converting between data structures in the relax data store and the XML. These are all the to_xml() and from_xml() functions you can find in the 'data_store' package. There have been zero optimisations here and, in some parts, the code is likely to be extremely inefficient (too much looping, inefficient ordering of loop nesting, etc.). This would be the best target for optimisations. And the loops are where you will squeeze out the most. To find the relevant functions/methods, just run: $ grep -r "def to_xml\|def from_xml" . --exclude-dir=".svn" To perform any optimisations, the test suite must be used to make sure that nothing breaks. If you notice a breakage in a save file you are using as a test for yourself while the test suite passes, then a new system test needs to be created using a heavily truncated save file. Anyway, you are free to optimise the save file creation and reading as much as you wish!
