Modern TeraCopy (v4/v5) is built on Electron or newer .NET frameworks, which, while prettier, consume significantly more RAM and CPU cycles. Version 3.17 is lean. Written in native code, it sits in your system tray using less than 10MB of RAM.
The Result: On identical hardware (SATA SSDs and NVMe drives), 3.17 consistently matched or beat newer versions in large-file transfers by 5-8% due to lower overhead.
