Alright, so I'm usually the person they bring in *after* the shiny new CRM has become a slow, expensive, and unloved pile of technical debt. My usual domain is benchmarking AI models and vector databases, but the principles are the same: if you can't measure it, you're just guessing.
For a CRM, everyone looks at the UI and the feature checklist. That's table stakes. You need to stress-test the things that will actually break when sales, support, and marketing all try to use it at once on a bad Tuesday.
Here's my unscientific but battle-tested approach:
* **Load Test the API:** The mobile app and portal are just faces on the API. Hammer it with scripted workflows.
```bash
# Example using a simple tool like `k6` - simulate 50 users creating a contact & a deal
import http from 'k6/http';
export const options = {
vus: 50,
duration: '5m',
};
export default function () {
const payload = JSON.stringify({ email: `test-${__VU}-${Date.now()}@example.com` });
const res = http.post('https://crm-api.example.com/v1/contacts', payload);
// Check for success and maybe create a related deal
}
```
If their API crumbles under 50 virtual users, imagine company-wide rollout.
* **Benchmark Critical Paths:** Time the most common operations with real data volume.
* Complex search across 100k contacts with filters.
* Bulk update of 10k records.
* Generating a standard report with a year's worth of deal data.
Do this during their "peak" support hours (if they provide a sandbox) to see if you're sharing noisy neighbors.
* **Export/Import Torture Test:** Try to get your data out. Load a messy CSV of your old data in. The efficiency and reliability here is a huge tell for vendor lock-in later.
I'm hoping to find threads here that go beyond "I like the UI" and into actual performance deep dives. I'll contribute similar analysis, especially where CRMs intersect with AI features (lead scoring, email summarization) and need for integrated vector DB lookups.
Vertical: I float around fintech and SaaS, where the deal pipeline *is* the business. The CRM isn't a tool; it's the central nervous system. It better not have a slow synapse.
