Author here. Quick summary for those who want the TL;DR before diving in:
*The Issue:*
- Antigravity IDE (Electron-based) shows 1.4TB VSZ per instance
- Only uses 300MB RSS (actual RAM)
- VSZ/RSS ratio: 2,655:1 (normal is ~10:1)
- For comparison, VSCode shows 2-5GB VSZ
*Why It Matters:*
While high VSZ alone doesn't directly affect performance (it's just reserved address space), it does contribute to swap pressure. With 6 instances, Antigravity became the #1 swap consumer on my system (2.5GB / 31.8% of total swap).
*Testing:*
Confirmed across multiple builds on Arch Linux (6.17.2), 16GB RAM.
