 ==> database
 * We should have a DB performance test suite to find important points to make faster,
 if we cannot measure, we cannot improve. 
- 
-* History, and  Summary-Description objects should be kept in seperate db files. This way 
-we  can have faster searches and probably faster access to packages and better memory footprint
-
-* For big objects with many member objects (Package, from pisi.metadata) we might investigate
-writing our own simple serialization routines for some objects like Conflicts or additionalfiles.
-
-* context singleton is a mess. Maybe we should consider another approach to access common db objects 
-
-* ComponentDB should not hold lists of Packages that belongs to it. A new index for components to package DB 
-should be enough.
-  
-* Current implementation of repository system is suboptimal. We add every package to a Dictionary as value 
-and repository name as key and add that dictionary to db. For example if I am adding package foo to 
-packages db, I am actually adding, a Dictionary with ["repotype", foo] to db.
-This is cheap, bloated and slow. We must have different repository databases for packages.

 currently PiSi wrotes everyting into logs which is not usefull. Also this information can be used for rollback and reporting.
