🔍 Assumptions Worth Discussing

I found 2 high-risk assumption(s) in this issue that might be worth making explicit. These aren't criticisms — they're invitations to align.

1. WebSocket connections are the cause

"Investigate the WebSocket connections for performance issues."

The assumption: The dashboard freezes are primarily caused by WebSocket connection issues (e.g., connection stalls, message backpressure, or reconnections).

Why it matters: If the root cause is elsewhere (backend query latency, heavy client-side rendering, main-thread blocking, or rate-limiting), focusing on WebSockets could waste time and delay the real fix. This also determines which teams need to be involved and what telemetry to collect.

Question for the team: Has anyone validated that WebSocket traffic correlates with freeze events (traces, p99 latencies, connection/reconnect logs, or metrics showing backpressure)? If not, can we gather traces and server/client metrics before deep-diving here?

2. Freezes are caused by data fetches

"The dashboard freezes frequently during data fetches affecting usability."

The assumption: The perceived freezes are caused by network/data-fetch operations rather than rendering, large synchronous state updates, or expensive client-side processing.

Why it matters: If freezes are due to UI work (e.g., rendering large lists, expensive reducers, or synchronous DOM operations), optimizing fetches won't resolve the user experience. A different set of fixes (debouncing, virtualization, web workers, or splitting state updates) would be required.

Question for the team: Do we have a reproducible profile (Chrome DevTools, React/Flamegraph, or telemetry) that shows the main thread is blocked during fetches? Can QA reproduce with a network throttling profile to isolate network vs. CPU issues?

🤔 Things Not Mentioned

• Repro steps / environments — Which browsers, auth roles, or datasets reproduce the freeze? — (frontend team / QA)
• Telemetry available — Which logs, traces, and metrics exist for the real-time stack and HTTP/WebSocket layers? — (observability/infra)
• Load characteristics — Does this occur under low single-user load or only at scale? — (SRE/backend)
• Recent deploys or changes — Any recent backend or client changes that coincide with the first reports? — (release owner)
• Suggested immediate triage steps — collect a sample client-side profile, WebSocket logs, and a backend trace for a freeze event.
