Tessabyte was previously known as TamoSoft Throughput Test and was distributed by TamoSoft Ltd. The product was acquired by Netmantics LLC in 2024.

The App

Building Reliable Network Infrastructure

Get the right software for the job— crafted for professionals who outgrew iPerf.

Here’s what you can do with Tessabyte:

Wi-Fi Speed Tests: Test wireless networks for throughput and reliability.
Network Capacity Tests: Assess the maximum data transfer rate that a network link can support.
Link Quality Analysis: Determine the quality of individual network links.
Stress Tests: Simulate high traffic loads and observe how the network behaves under congestion.
Quality of Service (QoS) Assessment: Evaluate how different traffic types are prioritized in the network.
Firmware and Hardware Updates Validation: Verify the impact of network device firmware or hardware upgrades.

LAN Bandwidth Tests: Don't take your local network speed for granted. Test, verify, and monitor.
Network Topology Planning: Understand how network design choices impact performance.
Comparative Benchmarking: Compare the performance of different network components or analyze how your network behaves at various times of the day.
Security Assessment: Evaluate the impact of security measures on network performance.
Load Balancing Verification: Test the effectiveness of load balancing in a network.
SLA Compliance Verification: Ensure that the network meets its Service Level Agreements.

Using AI Agents for Real Network Testing

AI agents are no longer limited to answering questions or writing code. In this experiment, Codex independently installed Tessabyte, discovered the command-line syntax, and performed real TCP/UDP network tests against local and cloud servers — all from a plain-English prompt. This is not consumer “speed test” automation. It is the beginning of intent-driven network testing.

10 Gigabit External Ethernet Adapters: Do They Really Deliver?

External 10G Ethernet adapters promise easy upgrades to multi-gig speeds, but do they actually deliver? We tested USB and Thunderbolt 10G adapters in a controlled lab setup and found a mixed picture. Some devices reached near line-rate TCP throughput, while others struggled badly. Even more interesting, UDP performance lagged far behind. Here’s what’s really going on under the hood.
