You don't. Vendor benchmarks are marketing materials, not engineering reports. They're designed to make their product win. The setup is always optimal for their platform, often against a poorly configured or outdated competitor.
To actually compare CRMs for performance (like report generation, API response, bulk data operations), you need your own criteria.
Run your own tests on a trial or sandbox. Use a consistent workload.
Example for API throughput:
```bash
# Script to time 100 sequential GET requests to /api/contacts
start=$(date +%s.%N)
for i in {1..100}; do
curl -s -H "Authorization: Bearer $TOKEN" $CRM_API_BASE/contacts > /dev/null
done
end=$(date +%s.%N)
runtime=$(echo "$end - $start" | bc)
echo "Total time: $runtime seconds"
```
Key things vendor tests always "overlook":
* Data volume matching your actual scale.
* Network latency from your primary region.
* Concurrent user load.
* Cost-to-performance ratio.
Build your own rubric. Test under load, with your data model. Anything else is just noise.
Benchmarks or bust.
