How to use mtr to find where packets are actually being dropped on a game server's path, read per-hop Loss% correctly, and tell real network loss from server-side choke.

AMX Mod X has no built-in per-plugin profiler by default, so here is the honest toolkit: bisection with amxx pause, reading meta list and stats, and isolating the plugin that is dragging your fps down.

What sys_ticrate really controls, why '1000 FPS' is mostly marketing, how server FPS caps updaterate, and how to measure and set it honestly on Linux.

The real performance difference between a dedicated server and a VPS for CS 1.6, when shared hosting is fine, and when steal-free dedicated hardware is worth the cost.

The engine's hard ceilings on precached models, sounds and generic files, the exact overflow errors they throw, and how to stay under them while keeping load times and memory sane.

How to pick a hosting region for the lowest ping to your actual player base, why peering matters more than raw distance, and how to test routes before you pay.

Why zombie mods are the heaviest CS 1.6 workload, how to tame precache from custom models and sounds, keep the edict count under control, and tune rates so knockback and infection feel crisp.

What CPU steal time is, how to read the %st field in top and vmstat, why an oversold VPS lags exactly at peak, and what you can actually do about it.

The rates, update ceiling, stable fps, plugin discipline and entity budget that let a full 32-player CS 1.6 server feel as tight as a 10-slot one.

How Linux CPU frequency governors work, why ondemand costs a game server latency, and how to set the performance governor so the core runs at full clock continuously.

How to pack multiple instances onto one box: per-core pinning, sane fps caps, separate configs and ports, the performance governor, and watching aggregate CPU, RAM and bandwidth.

How to pin an HLDS or ReHLDS instance to a specific CPU core with taskset for better cache locality, and why it matters most when packing many servers on one box.
