Inganta aikin Node ya fara da auna don neman ainihin toshe — kar yi zargi. Ka buga amfani da CPU, saki sako gida, da ƙoƙari, sannan ka yi amfani da gyara da ake yi. Tsari na zinariya: buga farko, gyara abin da jiya a jiya.

node --inspect app.js
Suna bayyana inda lokaci ya tafi — zane na iska yana nuni wane aiki nake karɓa CPU, don haka ka gyara abin da yake daidai.
// ❌ synchronous CPU-heavy work blocks ALL request handling
function handler(req, res) {
const result = heavyComputation(); // freezes the event loop → every request stalls
res.json(result);
}
Tunda Node yana da zartaccen zartaccen zarta don JS, duk wata aiki mai tsayi mai juyawa ke damje komai. Lura da saki sako gida mai damje (misali perf_hooks monitorEventLoopDelay); tashi mai karfi yana nuni wani abu ke damje saki. Gyara ta hanyar aiki na CPU zuwa zartaccen aiki ko jeri.
✓ Fix N+1 database queries — the most common real bottleneck (batch/join instead)
✓ Add caching (in-memory/Redis) for repeated expensive operations
✓ Add database indexes for slow queries
✓ Use streams for large data instead of buffering it all in memory
✓ Parallelize independent async ops with Promise.all (avoid await waterfalls)
✓ Offload CPU-bound work to worker threads (keep the event loop free)
✓ Use connection pooling for DB/HTTP
✓ Enable gzip/brotli compression for responses
Many "Node is slow" problems are actually slow DB queries (N+1, missing indexes)
or external API latency — profiling reveals this so you fix the real cause.

Auna kafin da bayan kowane sauyi don haka ka tabbatar cewa inganta ta taya aiki da gaske.
Aikin karɓa power shine mai tasiri kawai lokacin jagoran ta aunawa — inganta abin karaya abu ke danna wadata da kuma haɗawa.
Sanin nawa za ka buga (clinic.js/flame graphs/DevTools don CPU, saki sako gida mai damje lura, tunani jeri) ba ya ba ka neman ainihin toshe, wanda a Node galibi hake damje saki (gyara da zartaccen aiki) ko soraye jiya (N+1, wadanda bada jiya — a roba sai kundin.).
In yi tare da adawa, rawan, sawon, da tafi — da shawo da juna da jaddadi gwaje — da ana yin hanya gwajiyar-sannan-gyara ta wannan ne ke karkatar da aiki mai jiya zuwa sauri, mai rubutu.
