@baremind.healthWhen the streak tree in my app is fully grown, it’s drawn with about 590 watercolour SVG filters. Scrolling past it repainted every one of them, every frame. The fix was one line: translateZ(0) on the tree’s svg, so scrolling moves a finished picture.
@webperfreport.bsky.socialThe Technical Diagnostics and Business Outcomes Gap
When tools do not connect, people do.
And too often, senior specialists become human APIs between disconnected systems.

@nucliweb.netOne thing I’m experimenting with for a performance audit:
Using RUM data + @debugbear.com MCP to build synthetic tests based on how the product is actually used
RUM → real user behaviour → MCP → representative synthetic tests
@davatron5000.bsky.socialAny day I get to talk to people who enjoy and think about #webperf is a good day. Enjoyed talking with @benschwarz.bsky.social this week on the podcast.

@josephscott.bsky.socialOne more 👍 - the progressive rendering that I've seen from both AVIF and JXL look good, with those widely supported I'd ditch any other color blur pre-fill approach. #webperf
