7cd9d9d22a - enhanced DidYouMean computation using a faster count on index entries; this causes that results can be ranked better
- added limitations on DidYouMean result sets according to input and output string length

6388a58fc7 better memory management and slightly less (in total and temporary) RAM allocation:
- confirm that database objects that are not supposed to grow do not have a index memory management that is designed for growth
- changed index sorting method in such a way that it allocates less objects during quicksort
- database classes classes renaming (shorter, naming addresses that objects hold in RAM)
- added a large number of asserts to check if objects actually take the RAM that they should have

5924a0d851 - enhanced concurrency in database index access for multicore
- added statistics about database index caches in PerformanceMemory_p.html
- adoped many classes to use the new statistics
- added missing close statements

027b971bde fix for concurrent quicksort: catch jobs from ThreadPoolExecutor that had been rejected because of full processing queues.
Non-catched jobs may have been the cause for blockings and freezes in case of overloading during strong processing

93ea0a4789 enhanced remove operation in search consequences (which are triggered when the snippet fetch proves that the word has disappeared from the page that was stored in the index)
- no direct deletion of referenced during search (shifted to time after search)
- bundling of all deletions for the references of a single word into one remove operation
- enhanced remove operation by caring that the collection is stored sorted (experimental)
- more String -> byte[] transition for search word lists
- clean up of unused code
- enhanced memory allocation of RowSet Objects (will use a little bit less memory which was wasted before)

64f29f990e a collection of performance hacks and code cleanup:
- removed usage of URL-Caches which could have been a memory leak
- removed unused classes and methods
- removed not necessary synchronizations
- added synchronization hacks where possible
- fine-tuned crawling speed to prevent IO of balancer
- fixed a bug in IODispatcher that may have caused that no merges were done
- reduced number of parameters in very often called methods (compare methods)
- reduced complexity of data structures of now massively used HandleSet class
- reduction of new String() and getBytes() usage / new methods to support this transition

1a8a134e0c continuing String-hash - to - byte[]-hash redesign that was started in SVN 6775 and continued in SVN 6790
The result should be a less usage of new String() and less memory usage (since a String-encapsulated byte[] has 40 bytes overhead)

4a5100789f replaced _all_ size() == 0 with isEmpty() and all size() > 0 with !isEmpty(). The isEmpty() method is much faster in some cases, especially when used to access badly balanced hashtables where an size() operation becomes a large iteration.
