KNIME protocol runninf really slow

I have put together a large protocol to process HTS data that is running really slow.  the display is very slow to respond.  It is running on a Windows 7 machine and I've increased the Heap space to 3M.  Any ideas at to why this would be running so slow?  Thanks!

Hi Brad,


I've found that the most common cause of lag in the display of large workflow is high density of the highly connected nodes in the workspace.  This can be resolved by these steps:


  1. Pack highly-connected groups of nodes into metanodes, and
  2. Spread out the groups of nodes so that only the most related nodes are close to each other (i.e., avoid "folding" the workflow).
