Use (most) macOS style keyboard shortcuts on Windows

Make Windows PC's shortcut act like macOS (Mac OS X)

With this AutoHotKey script, you can use most macOS style shortcuts (eg, cmd+c, cmd+v, ...) on Windows with a standard PC keyboard.

Note that:

you shouldn't change the modifier keys mapping with keyboard DIP. This script assumes you use a standard PC keyboard layout, and wish to use shortcuts as if it was a mac keyboard layout.
To use cmd + shift + ↑ / ↓ / ← / → (select text between cursor and top / bottom / beginning of line / end of line), You should disable the Between input languages shotcut from Control Panel\Clock, Language, and Region\Language\Advanced settings > Change lanugage bar hot keys due to conflicting.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
