* introduced a new counter keeping track of the scheduled tasks - this prevent ↵Sebastian Thiel2010-06-071-2/+45
| | | | unnecessary tasks to be scheduled as we keep track of how many items will be produced for the task at hand. This introduces additional locking, but performns well in multithreaded mode. Performance of the master queue is still a huge issue, its currently the limiting factor, as bypassing the master queue in serial moode gives 15x performance, wich is what I would need
* improved testing to test the actual async handling of the pool. there are ↵Sebastian Thiel2010-06-071-0/+11
| | | | still inconsistencies that need to be fixed, but it already improved, especially the 4-thread performance which now is as fast as the dual-threaded performance
* task: Fixed incorrect handling of channel closure. Performance is alright ↵Sebastian Thiel2010-06-071-3/+21

* Plenty of fixes in the chunking routine, made possible by a serialized ↵Sebastian Thiel2010-06-061-1/+1
| | | | chunking test. Next up, actual async processing
* First step of testing the pool - tasks have been separated into a new module ↵Sebastian Thiel2010-06-061-0/+144
including own tests, their design improved to prepare them for some specifics that would be needed for multiprocessing support
