Human latency is how fast a system responds to a real user — from click to visible change.

12 Hardcore Server Optimizations We Actually Use

Flask · Python · JavaScript · Nginx · Gunicorn · PostgreSQL

01

TCP Fast Open

Allows data in the SYN handshake, reducing round-trip latency on repeat connections.

02

BBR Congestion Control

Modern congestion control tuned for throughput and latency under real network conditions.

03

Raised File Descriptor Limits

Kernel, user, and Nginx limits tuned to eliminate hidden concurrency ceilings.

04

Nginx Worker Affinity

Workers pinned to CPU cores to reduce cache thrashing and context switching.

05

Sendfile + TCP_NOPUSH

Optimized packet batching for fast, efficient payload delivery.

06

Gunicorn Preload + COW

Application preloading for memory sharing and faster worker spawn.

07

Worker Class by Workload

Sync, threaded, or async — selected based on real I/O behavior.

08

Socket Keepalive Tuning

Prevents zombie connections without disrupting legitimate clients.

09

Selective Nagle Disable

Latency-critical endpoints bypass buffering delays.

10

Zero-Copy Static Delivery

Nginx serves static assets directly from kernel space.

11

Systemd + Gunicorn Hardening

Socket activation, restart policy, and CPU accounting.

12

Human-Perceived Latency Metrics
