rmannibucau opened a new pull request, #18107:
URL: https://github.com/apache/iceberg/pull/18107

   Follow up of the [list 
issue](https://lists.apache.org/thread/hstl6z6qp55hxgdlljpc5xg8wc3kq800) with 
the home page eating 100% of one core.
   
   The Lottie player kept rendering even when the animation was offscreen, and 
its SVG renderer burns a core while visible. Replacing it with a pre-rendered 
muted looping video (rendered from the same Lottie file) drops this to a few 
percent, and removes the vendored, now-archived lottie-player bundle.
   
   New animation (`site/docs/assets/videos/hidden-partitioning.mp4`, 860x744, 
40s loop, 296 KB):

   Lottie vs video (Chrome on macOS, visible window, 15s average, % of one 
core):
   
   | Scenario | Lottie | Video |
   |---|---|---|
   | Live home page, animation offscreen (renderer) | 38% (9% with Lottie 
blocked) | n/a, paused by browser |
   | Live home page, animation on screen (renderer + GPU) | 38% + 71% (11% + 7% 
with Lottie blocked) | |
   | Animation alone on a blank page (renderer + GPU) | 30% + 97% | 1% + 4% |
   | Main-thread task time per 10s, animation alone | 1966 ms | 7 ms |
   
   Format comparison, same setup:
   
   | Format | Size | CPU (renderer + GPU) |
   |---|---|---|
   | Lottie (before) | 440 KB | 30% + 97% |
   | MP4 (H.264) | 296 KB | 2% + 6% |
   | GIF (860px, 30fps) | 12.8 MB | 6% + 9% |
   | Animated WebP | 4.4 MB | 8% + 5% |
