Stress test
Keep your connection under continuous load for up to 12 hours.
Download + upload runs both directions at once, sharing the total streams equally. For example, 96 streams means 48 downloading and 48 uploading.
This can transfer many GB and use all available bandwidth. It continues while you use other tabs, as long as the browser keeps this page active. Stop, closing or reloading this page, or going offline ends it. Sleep or tab suspension may interrupt it. 32 streams is the default; 64 and 96 are heavier loads.
