System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

  1. Clarify and agree on the scope of the system
  • User cases (description of sequences of events that, taken together, lead to a system doing something useful)
    • Who is going to use it?
    • How are they going to use it?

ntk148v / linux_memory_control_to_avoid_swap_thrashing.md
Created November 28, 2019 09:41 — forked from JPvRiel/linux_memory_control_to_avoid_swap_thrashing.md
Notes on linux memory management options to prioritize and control memory access using older ulimits, newer cgroups and overcommit policy settings. Mostly as an attempt to keep a desktop environment responsive and avoid swap thrashing under high memory pressure.

Overview

Some notes about:

  • Explaining why current day Linux memory swap thrashing still happens (as of 2016).
  • Mitigating "stop the world" type thrashing issues on a Linux workstation when it's under high memory pressure and where responsiveness is more important than process completion.
  • Prioritizing and limiting memory use.
  • Older ulimit versus newer CGroup options.

These notes assume some basic background knowledge about memory management, ulimits and cgroups.
