Issue:
- generating output files using HDA Processor gradually slows the generation.

Example - looking at the file timestamps:
at 12:00 it generated 30 files
at 12:01 it generated 20 files
at 12:02 it generated 15 files
at 12:03 it generated 10 files
and so on..
at 12:10 it generated 1 file (something like this is happening)

but if I dirty and cook the node, the timing seems to be fast again, until it gradually slows down again.

Setup:
- H18.0 (unable to use higher version due to project version dependency)
- Local Scheduler
- using COP HDA that generates images.
- the COP HDA contains a SOP Network needed by the COPs.
- the SOP Network contains a python node that reads in info from an external software.
- i'm mainly using HDA Processor service (tried pools 1, 2, 6, 8)
- i tried batching, but i'm getting "Unable to Cook Node" errors


Question
- i wonder if i need to have a process that can clear or reset some cache/memory in order to get more or less consistent generation times?
- are there other factors that i may need to look into?
