It looks like “Speed Test” in Roblox was likely a small developer-made game or feature that people used as a rough network/loading-speed benchmark rather than an official Roblox system. A 2014 Roblox Developer Forum post describes it as a terrain-loading “speed test” that times how much terrain your client can load before disconnecting.

What likely happened

The main clue is that the game concept appears to have been informal and experimental, not a long-running official Roblox feature. In the forum discussion, the idea is explained as a way to measure how much terrain loads before timing out, which suggests it was more of a novelty project than something Roblox maintained as a core game mode.

Why people may think it “disappeared”

A few likely reasons:

  • It may have been renamed, replaced, or removed by the creator.
  • Roblox games and experimental test places often go inactive if the developer stops updating them.
  • Older forum references can survive even after the original experience is gone.

Current Roblox context

If you were actually looking for a current Roblox speed-related experience, recent results show active games like +1 Speed Keyboard Escape , but that is a different title and not the old “speed test” concept. Those sources also note that the game’s code system recently changed, which is probably unrelated but shows how quickly Roblox experiences can be updated or altered.

Most likely answer

So, the most likely explanation is that Speed Test in Roblox was an old community/project experience that is no longer active or no longer easy to find , rather than a feature that Roblox formally removed. If you meant a specific game named “Speed Test,” I can narrow it down by title, creator, or a screenshot.
