Hi @reiabreu

I am currently working asynchronously to propose a code change aimed at stabilizing jitter without impacting throughput or increasing latency.

Unlike the discrete event simulation results, the feedback tuple being evaluated with storm perf is currently degrading performance.

To address this, I am trying to create a feedback tick stream to replace the current ratio-based mechanism.

If performance remains degraded even after this modification, I will post an update and either close the PR or ask for further help in Dev maillist.
