Hardware

If you are interested, see also my previous setup.

I use a Mid 2013 11-inch MacBook Air at home.

I use Logitech Performance MX mice with all three of them, though for the last one is usually just the trackpad. I have recently started using a Logitech MX Master and decided to only buy that from now on.

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
