Performance & Preview Enhancement Suggestions for Blender Compositor

I am a professional compositor who actively uses the Adobe Suite, but I also really appreciate the flexibility of Blender's native node system. Unfortunately, in my experience, Blender Compositor is still not quite capable enough for compositing PNG Sequences or similar assets, as it feels noticeably slow and resource-heavy.

To improve productivity, I would like to propose two specific enhancements:

1. Implement preview scaling options (Quarter, Third, Half, Full) similar to Adobe After Effects. This would significantly speed up look development and review processes by allowing artists to work interactively without waiting for full-resolution renders.

2. Improve node calculation efficiency and cache memory management so that Blender Compositor becomes lighter and more responsive, especially when handling multiple high-resolution image inputs or complex node trees.

I hope this feedback can be taken into consideration for future releases. Thank you for the team's hard work and continued dedication to the creative community!
