Taverna 3

When the cache is full, the data processing slows down enormously

Details

Description

With the attached workflow, it runs quite quickly through the first few iterations of create report but then slows down, possibly once the cache becomes full and read/write to the database starts. It is not clear how this can be improved/

Solution:
Run Taverna in JProfiler and trace what might be slowing down. If possible - fix.

Test:
Run workflow again and check that slowdown does not occur.

Could be caused by the provenance rather than the reference management. If there are a lot of iterations the back-patch overhead seems to increase over time.
