Mabadiliko ya Tabianchi

Saa ya kugeuka ya hisia ilipoteza seti ya 200ms kuandika sehemu katika React. Hiyo ni njia ya uaminifu ya kujenga bar ambayo lazima kufuatilia tarehe ya mwisho ...

measure() runs on each scroll and resize event and built a fresh state object every time, so the toolbar re-rendered whether or not anything about the image had...

Opening a chat window cost seven requests before a message rendered — history, members, receipts, mark-read, the unread snapshot, the counterpart's avatar and t...

useUserInfo held its session in three useState cells. It has 187 call sites and roughly 27 of them are mounted for the whole session — the nav, every shell prov...

Both faces are preloaded on every route, so the format is paid on every first visit. 134,132 B of WOFF became 112,252 B of WOFF2 — 21,880 B, a 16% cut. That is...

The market settings page imported all 24 tabs statically, so every market shipped every tab — a retail market carried the seven mortgage tabs, the four personal...

The slideshow preloaded every wallpaper behind a single Promise.all, so nothing painted until the LAST image in the set had settled. On a tenant with a dozen ba...

Seven independent /api/user-info calls fired on a cold authenticated load, each one asking for the member id a sibling was already asking for at the same moment...

useUserInfo has 194 call sites, roughly a dozen of them mounted for the entire session — the nav, the shell providers, the launchpad. Each instance armed its ow...

MemberListProvider returned null until its mount effect ran, and it sits above NavTop AND {children} — so that one line kept the ENTIRE authenticated applicatio...

Six call sites read the email store with a bare `useEmailStore()`. In zustand that subscribes to the WHOLE store, so any change anywhere in it re-renders the co...

UnreadContext published a fourteen-member object literal as its context value, so React saw the context change on every render of the provider and woke every co...

Two always-mounted providers ran a one-minute poll with no visibility gate. LegalPackageCount had none at all; TrainingPendingCount had a visibilitychange re-re...

The softphone opened its SockJS/STOMP connection to media.<domain> unconditionally at boot. getCapabilities() is awaited a few lines above and is the backend's ...

getRequestConfig runs per request, and for any non-English member it called mergeWithFallback over the entire 23,252-key catalogue every time — rebuilding a res...

Batch 5 of the client-side performance audit. MessageList maps every loaded message to a MessageBubble, and MessageBubble was not memoized. With 300 messages o...

Batch 4 of the client-side performance audit, and the last of the big ones. app/globals.css opened with two @imports of ag-grid's stylesheets, and the root lay...

Batch 3 of the client-side performance audit. The root layout passed every message to NextIntlClientProvider on every route. The catalogue is 1.05 MB compact —...

Batch 2 of the client-side performance audit. As with batch 1, nothing a member can see or do changes. The tool registry imported all ten tool windows eagerly,...

Batch 1 of the client-side performance audit. Every change is behaviour-preserving; nothing a member can see or do is different afterwards. I18nProviders impor...

The grid fetched every lead in the org and narrowed it in a ~300-line useMemo. Measured on production 2026-08-20: 1,427 leads fetched so seven could be shown, 2...

The mail badge needs one integer and was fetching every folder in the mailbox to find it, which on the IMAP providers is the most expensive call the mail backen...

Two round trips still sat in front of a rendered inbox, and by this point they were the only thing left there — the folder tree and the first page already arriv...

Three more things standing between opening /messages and seeing mail. Nothing was requested until the bundle had landed. /messages pulls several megabytes of J...

Three things were slowing /messages down before a single message was fetched. Every email call made a round trip to /api/generate-otk first and sent the result...

Dedup worked — the server logged 'linked WITHOUT upload' and 358 MB never left the machine — but the member still waited, because computing SHA3-256 alongside B...

Every edit-style autosave (name fields, employment, assets, liabilities, REO, declarations, military, HMDA demographics, originator) used to issue a full mortga...

- Bypass OTK generation in the MediaService proxy route: forward the *** cookie directly instead of generating a one-time key, removing 4 Redis round-trips ...

- Cache getCurrentMemberId() result in a ref to avoid repeated /api/user-info calls on every WebSocket message and typing indicator - Parallelize message hist...

- docker-container driver adds initialization overhead - For fast builds (<3min), docker driver is more efficient - Removed cache options (not supported by dock...
