scaling
From the author
Use when traffic is growing or about to spike and the system bends under concurrency — deciding what to add and in what order (cache, connection pool, async queue, read replica, more instances) and proving it with a load test against explicit RPS and p95 targets rather than guessing. NOT making one slow request faster or profiling an N+1 (that is `performance`), NOT race-free Redis caches, locks and queue semantics (that is `redis`).

- cachingnahid-sparktales/agent-dispatcherDecide what to cache, at which layer, for how long, and how it gets invalidated — before any cache is added. Use when someone proposes caching to make a read path faster, when stale or cross-user data is suspected, when adding a TTL or a Redis/CDN layer, or when reviewing a change that introduces one. Not for fixing a slow query or an N+1 (do that first — a cache over a bad query hides it), and not for HTTP header tuning with no server-side store.Other★ 59
- performance-capacitymajiayu000/spellbookPlan, diagnose, and verify performance budgets, latency targets, load tests, capacity estimates, bottleneck analysis, caching strategy, query efficiency, queue throughput, and regression gates. Use when a feature may be slow, a system must scale, a performance regression is suspected, or release readiness depends on throughput, cost, memory, CPU, or response time.Testing★ 288
- sentry-load-scalejeremylongshore/tons-of-skills-marketplaceScale Sentry for high-traffic applications handling millions of events per day. Use when optimizing SDK performance at high volume, implementing adaptive sampling, managing quotas and costs at scale, or deploying Sentry across multi-region infrastructure. Trigger with phrases like "sentry high traffic", "scale sentry", "sentry millions events", "sentry high volume", "sentry quota management", "sentry load test".Testing★ 2.9K
- vercel-load-scalejeremylongshore/tons-of-skills-marketplaceLoad test and scale Vercel deployments with concurrency tuning and capacity planning. Use when running performance tests, planning for traffic spikes, or optimizing serverless function scaling on Vercel. Trigger with phrases like "vercel load test", "vercel scale", "vercel performance test", "vercel capacity", "vercel benchmark".Testing★ 2.9K
- performance-optimizationaddyosmani/agent-skillsOptimizes application performance across frontend, backend, queries, and databases. Use when performance requirements exist, when you suspect performance regressions, when Core Web Vitals or load times need improvement, when N+1 query patterns need fixing, or when profiling reveals bottlenecks.Design★ 110.1K
- optimizing-performanceCloudAI-X/claude-workflow-v2Analyzes and optimizes application performance across frontend, backend, and database layers. Use when diagnosing slowness, improving load times, optimizing queries, reducing bundle size, or when asked about performance issues.Data★ 1.4K
