orbiter	addecdb18c	simplified code, removed one unused method in all implementing classes ... git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5972 6c8d7289-2bf4-0310-a012-ef5d649a1542	2009-05-21 23:53:01 +00:00
orbiter	65784eb656	- more efficient comparator calls ... - fix for http://forum.yacy-websuche.de/viewtopic.php?p=13331#p13331 git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5714 6c8d7289-2bf4-0310-a012-ef5d649a1542	2009-03-14 00:07:37 +00:00
orbiter	f6d989aa04	added new class RowSetArray which arranges RowSet objects like Elements in a hashtable, but still provides the functionality of sorted enumeration. The new class is now integrated into the ObjectIndexCache, which is the core class to provide index functions to all database files. The new index access is about twice as fast as before. This has strong speed enhancement effects on all parts of YaCy. ... The speed of the kelondro indexing class ObjectIndexCache can be compared with Javas standard TreeMap with the main method in IntegerHandleIndex. The result is, that the kelondro indexing needs only 1/5 of the memory that TreeMap uses! In exchange, the kelondro classes are slower than TreeMap, about four (!) times slower. However, this is not so bad because the better use of the memory is a strong advantage and makes it possible that YaCy can maintain such a large number of document (> 50 million) in one peer. git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@5705 6c8d7289-2bf4-0310-a012-ef5d649a1542	2009-03-12 23:05:18 +00:00
