What's the real-world throughput limit on a single Gateway? Need numbers.

Hey everyone, I've been running NordLayer in our sandbox environment for about three months now, specifically to evaluate its fit for our marketing tech stack when we need secure, segmented access to our cloud tools. I'm deep in the weeds on performance because we often push large analytics exports and sync data between platforms like HubSpot and our data warehouse.

My main question is about **real-world, practical throughput on a single Gateway**. The specs page mentions "high-speed" connections, but I need to map this to actual use cases. For instance, if my team is running a synchronized segment sync via an automation platform through the VPN, what's the actual ceiling?

Here's what I'm trying to figure out:
* **Sustained transfer rates:** What's a realistic Mbps/Gbps range you've consistently measured for a single file transfer or data stream over a Gateway connection? Not the peak, but what you can rely on during a 30-minute operation.
* **Concurrent user impact:** If 5-10 marketing ops people are all using the same Gateway—some in Salesforce, some in Marketo uploading lists, others pulling from GA—does throughput per user drop significantly? How is the bandwidth managed?
* **Geographic variability:** I get that a Gateway in Frankfurt vs. one in SF will have different limits. What's been your experience comparing regions? Is there a noticeable performance hierarchy?
* **Protocol overhead:** In your testing, have you seen a major difference in effective throughput for different types of traffic (e.g., SFTP vs. standard web traffic)?

I've run some basic tests myself, and the numbers seem to fluctuate based on time of day, which is expected. But I'd love to hear from others who have stress-tested this in a business context, especially with marketing automation or CRM data in transit. Are we talking 50 Mbps, 200 Mbps, or something else as a stable baseline?

Any hard numbers, testing methodologies, or even anecdotal "it choked when we tried X" stories would be incredibly helpful. I'm putting together a report for our IT team, and real community data beats marketing copy any day.
