Throughput Test & More

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.

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.

How many Wi-Fi clients can a single access point really support? The answer isn’t as simple as a number. In real networks, every device competes for the same airtime, and as more clients join, each gets a smaller slice of the pie. In this article, we look at how Wi-Fi capacity actually works — and why adding “just a few more devices” can quickly turn a fast network into a slow one.

If you have ever validated a Wi-Fi upgrade in a quiet lab and then spent the next week explaining to users why “everything looks fine on our end,” you already know how this story ends. The lab test measured the PHY at its best. The real network lives and dies by airtime. This post is for Wi-Fi engineers. It is about understanding why that number collapses at 10:30 AM on a Tuesday, and how to test in a way that predicts what users will actually experience.

Under light load, almost any LAN or Wi-Fi system looks perfectly fine. The switch blinks, the AP purrs, and nothing seems wrong. But once you apply enough load, networks begin revealing their traits.

When you read “1 Gbps” on a spec sheet, it’s tempting to assume that applications will send and receive data at 1 Gbps. In practice, that almost never happens outside of a clean LAN.

You think your network’s solid—until you run a UDP test and it looks like half your packets vanished into thin air. Don’t panic. Nothing’s broken. UDP just plays by different rules.

So, you’ve been using iPerf for a decade and a half. It has become something of an industry standard, and that reputation is largely well-deserved. But…

If you’ve been around networks long enough, you know the feeling: You set up your test gear, run your favorite throughput tool, stare at the chart, and think… “Well, that’s… something.” For years, one of the best ways to measure that “something” was TamoSoft Throughput Test. It was dependable, straightforward, and it told you exactly what your network could (or couldn’t) deliver. It became the Swiss Army knife in countless engineers’ toolkits. But here’s the thing: technolog

All is well. Meanwhile, your VoIP calls are melting. Let’s be honest: we’ve all run a speedtest in our browser at some point. Maybe you typed “ internet speed test ” into Google. Maybe you clicked that shiny internet speedometer on Ookla’s site and watched the needle spin. And hey — that’s fine. That’s how most people check their connection. But here’s the thing: if you’re a network engineer, IT pro, or anyone responsible for making networks behave… you’re not a civilian. A
