Based on the measurement of resource consumption of various editors using an 887MB log file, IntelliJ IDEA Community Edition and the default Notepad showed excellent performance.
The loading time and CPU/GPU/memory usage of various editors such as Zed, Sublime Text, and VS Code were compared and analyzed.
In particular, it was confirmed that Zed has AI plugin support and hx is a modal editor that is a successor to nvim, each with its own characteristics.
To explore the editor and test resource consumption based on the editor/viewer, I ran an 887MB log file.
Zed: Loading time 12 seconds, CPU usage 24.6%, GPU usage 0%, Memory usage 8,224.0MB
Sublime Text: Loading time 22 seconds, CPU usage 1.4%, GPU usage 0%, Memory usage 1,805.8MB
Visual Studio Code: Loading time 13 seconds, CPU usage 14.0%, GPU usage 1.4%, Memory usage 368.2MB
Notepad.exe: Loading time 18 seconds, CPU usage 8.0%, GPU usage 0%, Memory usage 1,354.5MB
klogg log viewer: Loading time less than 5 seconds, CPU usage 0%, GPU usage 0%, Memory usage 95.4MB
IntelliJ IDEA Community Edition: Loading time less than 5 seconds, CPU usage 0%, GPU usage 0%, Memory usage 881.3MB
nvim.exe: Loading time 124 seconds, CPU usage 24.0%, GPU usage 0%, Memory usage 1,021.2MB
Notepad++: Loading time less than 5 seconds, CPU usage 2.1%, GPU usage 0%, Memory usage 1,128.0MB
hx.exe: Loading time less than 5 seconds, CPU usage 0%, GPU usage 0%, Memory usage 1,137.3MB
IntelliJ showed surprisingly fast performance in handling large files, and Windows' default Notepad also performed well. Although some programs took a long time to load, overall usability after loading was satisfactory for all.
Zed is not yet officially released on Windows, so I tested it by building the latest code directly. Notably, it has built-in AI plugins and supports Copilot, Claude, and more.
hx (Helix) feels like a successor to nvim, and it's a modal editor. Although it currently lacks plugins, making it impractical for real-world use, its performance is comparable to the latest editors.
