• task: vac:dst:waku:2025q4-waku-evaluation:nwaku-v0.37-bandwidth-regression

Summary:

• Relatively low bandwidth utilization is seen with rendezvous set to false.
• v0.37-rc, v0.37-401cf194, v0.37-rc-4, v0.37-rc-3 show highest bandwidth utilization.
• v0.37-6cf36440, v0.37-9223fac8, v0.37-rc-4 show lowest bandwidth utilization.

Small packet loss is seen in some experiments
