How do I make search-as-you-type fast with edge n-grams in Elasticsearch?
Drop wildcard for autocomplete; build the prefixes at index time with edge_ngram and keep a standard search analyzer so a keystroke is a plain term lookup.

How do I stream 2-5 GB file downloads without blowing up PHP's memory?
Serve 2-5 GB files outside PHP via a presigned URL or X-Accel-Redirect; if it must go through PHP, chunk it with readStream and turn off buffering.

How do HTTP/2 and HTTP/3 (QUIC) improve API performance?
Turn on HTTP/2 today, since multiplexing collapses 4-5 requests per screen onto one connection; add HTTP/3 for a mobile audience and drop domain sharding.

Which PgBouncer pooling mode should I pick — Session, Transaction, or Statement?
Pick Transaction mode for a web fleet; the price is protocol-level prepared statements, so disable them in the app or turn on PgBouncer 1.21+ support.

How do I prevent a Redis cache stampede (thundering herd) — mutex lock or XFetch?
A single-flight lock plus TTL jitter covers most cases; reach for XFetch only when recompute is truly expensive, and add stale-while-revalidate either way.

How do I cut GC pressure in Go with sync.Pool and escape analysis under load?
The enemy behind the pauses is allocation rate: kill the top allocator with pprof, pool the hot path with sync.Pool, and tune GOGC last, not first.
