Part 3 - Looking for feedback on our Tor relay configuration decision:
Looking for guidance on optimizing server / bandwidth spending for Tor guard /
middle relays across datacenters.
Our current setup:
- All same cost: Three servers in different datacenters, each with 10 Gbps
unmetered bandwidth.
- Identical hardware/software: Each server has 128 threads, 512GB–768GB RAM,
and the same software stack.
- Diversity benefits: Each server hosts fewer than 10 other relays, enhancing
overall network diversity.
- Primary differences: Geographic location and upstream peering/routing.
Current Utilization:
- Server 1: 2Gbps utilized (20% utilization)
- Server 2: 6Gbps utilized (60% utilization)
- Server 3: 8Gbps utilized (80% utilization)
Overall, using 16 Gbps out of 30 Gbps purchased -- roughly half our bandwidth
is idle / "wasted".
Assuming we can't significantly optimize these servers any further and given
the significant under utilization on Server 1 (80% idle) and Server 2 (40%
idle), what would you do in this scenario? Some options we’re considering:
- Consolidation: Paying only for the servers with the highest utilization.
- Repurposing: Allocating the idle bandwidth to another purpose that benefits
Tor (or a similar effort).
- Reinvestment: Using the funds from Servers 1 and 2 to acquire additional
high-utilization capacity (e.g., more of Server 3 configuration) to boost our
overall contribution closer to 24 Gbps.
- Other strategies: Any alternative approaches you might suggest.
Appreciate any thoughts or best practices to help reduce wasted expenditure
while maximizing the utility of our available resources.
Thanks for your insights!
