W30 - Performance & Manpower

• Some performance considerations for the checkout.The project refactored with Vue has an obvious disadvantage in bundle size. From a product perspective, the checkout has specific characteristics: rigid presentation and high-frequency use. In Q3 we need to propose targeted strategies tailored to the checkout’s use cases. Broadly there are three areas: first, reducing bundle size — there is still room to shrink the initial-screen bundle. Second, caching — the checkout is a high-frequency page, and an efficient caching strategy should yield immediate metric improvements. For first-time checkout openings, consider adding prefetching. Third, some relatively aggressive, large-scale experiments. For a checkout with low customization and exhaustively enumerable displays, I found a potentially suitable optimization approach in the community,Offline Prerender (OPR). This is a Prerender-based approach that schedules the task of rendering HTML static files in an offline service; when a user visits, the corresponding static file is served directly.

• Some thoughts on staffing the B-side checkout team.As the B-side checkout scales in integrations, payment features expand, and platform capabilities improve, I often find myself switching among many small tasks — assisting in troubleshooting daily production issues, developing minor requests, and so on. Given the current workload for B-side checkout, two full-time engineers is somewhat more than enough, but adding an intern could serve as backup and strengthen organizational resilience while freeing me to focus on larger, higher-value work. Right now I’m short on bandwidth for planning and data monitoring.
