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 ...

Applying DDL bumps the catalog version, and backends still holding the old one fail their next statement with SQLState 40001 until they are recycled. The last o...

Its own comment said it existed so a page could paint the employer "without pulling every advert down with it", and the line under that comment called board() —...

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...

The search index row's key is assigned rather than generated, so handing a built entity to save() was a merge: Spring Data SELECTed the whole row — body text in...

A node inside a tree already knows where it is -- its position is the tree. Sending the ancestor chain on each one meant every article carried two ancestor refs...

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...

Two costs, both paid on every single open of a chat window. ?since on GET /sessions/{guid}/messages. A window being reopened wants the messages after the one i...

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...

Every document list ran an esign_templates lookup for EACH row — 100 per page — to answer "is this an original that happens to carry a design". That was how the...

/leads/available-summary returns three things — hasAcceptable, hasAcceptableCredit and one example product — but visited every market x product pair regardless,...

Country alone was the only index on an 80,429-row table, and neither real query used it well. Measured on production: city resolution (country + subdivision)...

GET /changelog/public/stats loaded all 16,571 commit logs as entities and tallied them in a Java loop to produce two small maps and a total. It takes no authent...

Three findings from an endpoint-by-endpoint audit, each measured against production rather than inferred. member_rights_applied declared no indexes at all whil...

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...

GET /api/security/leads returned every lead in the organisation. It now takes page/size/sort plus the filters the grid actually uses, and returns a page with a ...

Loading /leads took 23.3 s at 1,427 leads. 23.3 s of that was the HIPAA audit trail: recordLeadList writes one phi_access_log row per lead returned, and each on...

server-nonce.js asks upstream for `identity` so the HTML can be stamped with a CSP nonce without a decompress/recompress round trip, then recompresses on the wa...

Four components waited for the main thread to go quiet before doing their work — the toast/consent bundle, the scroll chrome, the touch target sweep and the ref...

The nav's scrolled/at-top state came from a scroll handler that read window.scrollY, and the mount effect called that handler synchronously during React's commi...

The flagged chunk is react-dom, and I checked it properly before concluding anything: it is the production build (no dev markers, and the profiling hooks `injec...

Two findings, and the second one was mine. THE DOCUMENT TOOK 1,259 ms BECAUSE OF THE NONCE WRAPPER. Measured against the live site: the HTML answered in ~900 ...

All 26 elements Lighthouse listed under "avoid non-composited animations" were the same mistake in four places: animating a paint property. Measured with Chrome...

Implements the request-budget report. Measured the same way it was written — Chrome over the debugging protocol, mobile emulation, sixteen-second window. 6...

Chasing "make fewer HTTP requests" found two real things, and the second is much larger than the audit that led to it. THE HLS BRANCH NOBODY WAS TAKING. HeroSt...

Two scroll listeners on the homepage read `scrollHeight` per event. That is a layout query, and this page is the worst place to make one repeatedly: its section...

The homepage renders 94 elements carrying `backdrop-filter: blur(20px)`. Every one is a separate compositing layer that has to read back everything painted behi...

Three changes, all removing work from the window where the page is being judged. `(pages)/layout.tsx` carried `"use client"` and never needed it — no state, no...

The LCP breakdown is where the remaining time is, and its two loading subparts — 270 ms of resource load delay, 500 ms of load duration — are a priority problem...

Framer was the chunk Lighthouse named. GSAP is the one it did not, because it arrives late enough to fall outside "unused JavaScript" — but it is 69 KB in its o...

"Reduce unused JavaScript" has named the same 35.4 KB chunk in every report, and it is Framer Motion. It is not an eager script on the homepage, which is why it...
