Questions to answer after the VE varying size tests

A TODO for PR #888
Consider in the #578

Memory usage seems to indicate a trend up.
- Run baseline for for longer to clarify.
During the 5 minute interval to clean up the mempool, some nodes actually have the mempool expanding.
- Hypothesis: these are seed nodes, which frequently have to catch up. We need to investigate further; possibly filter messages in seed nodes.
If the mempool size drops quickly, why is the memory slow to empty? Slow GC?
- The load created by the load generator seems to be a small part of the actual load.
Runs with larger extensions use many rounds.
- Check the effect of running with longer timeouts.
The app causes proposals to be large, not only VE.
- Run with the app modified so the proposals are not increased?
what is the effect on block sizes?
- blocks are of size 2 x Extension Size x Quorum size.
