Performance issues

Diagnose slowness, large pages, and network constraints.

Performance issues feel like “the app is slow” but usually break down into network, rendering, or data volume. Gather one slow trace with timestamps before escalating—patterns matter more than one-off complaints.

Browser

Disable heavy extensions and test with hardware acceleration toggled.

Profiles

Try a fresh browser profile with only default extensions. Ad blockers and password managers sometimes inject scripts that delay paint.

Content

Huge embedded media slows load—lazy load or host externally when possible.

Tables and charts

Large datasets should paginate or virtualize. If the editor feels fine but read mode lags, the DOM size is a likely culprit.

Network

Corporate proxies sometimes buffer WebSockets—ask IT for allowlist guidance.

VPN

Split tunnel vs full tunnel changes latency paths. Compare latency with VPN off (if policy allows) to isolate the network layer.
