Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

WSL2 with GUI using Xvnc

In this tutorial, we will setup GUI in WSL2, and access it using VNC. No additional software outside WSL (like VcXsrv) is required, except, of course, a VNC Viewer (RealVNC, TightVNC, TigerVNC, UVNC, etc, all of them might work flawlessly).

The key component we need to install is tigervnc-standalone-server.

For this setup, I will use Ubuntu 20.04 LTS (Focal Fossa, unfortunately 22.04 does not work), and install GNOME Desktop. Since the key components aren't bound to Ubuntu or GNOME, you can use your favorite distro and GUI. Check the Sample screenshots section for examples.

So let's go. First, we need a working WSL2 installation.

技術文書の書き方

このメモは、私（@ymmt2005）が長年にわたってソフトウェアプロダクト開発に関わってきて 2022年現在こうしたほうが良いと考えているベストプラクティスです。

科学的な分析等に基づくわけではない経験則であるため、今後も随時見直すことがありますし、ここに書いてあることが常に正しいわけでもあらゆるソフトウェア開発に適するわけでもありません。

しかしながら、実務経験が豊富で、モダンな技術スタックに明るいエンジニアの経験則は一定の役に立つのではないかと考えて記します。
