On every keymap notify event, the keymap should be refreshed, which fetches the required X11 atoms. A big keymap might have a few hundred of atoms. A profile by a user has shown this *might* be slow when some intensive amount of keymap activity is occurring. It might also be slow on a remote X server. While I'm not really sure this is the actual bottleneck, caching the atoms is easy enough and only needs a couple kb of memory, so do that.

libxkbcommon
libxkbcommon is a keyboard keymap compiler and support library which processes a reduced subset of keymaps as defined by the XKB (X Keyboard Extension) specification. It also contains a module for handling Compose and dead keys and a separate library for listing available keyboard layouts.
Quick Guide
See Quick Guide.
Building
libxkbcommon is built with Meson:
meson setup build
ninja -C build
To build for use with Wayland, you can disable X11 support while still using the X11 keyboard configuration resource files thusly:
meson setup build \
-Denable-x11=false \
-Dxkb-config-root=/usr/share/X11/xkb \
-Dx-locale-root=/usr/share/X11/locale
ninja -C build
API
While libxkbcommon's API is somewhat derived from the classic XKB API as found in X11/extensions/XKB.h and friends, it has been substantially reworked to expose fewer internal details to clients.
See the API Documentation.
Dataset
libxkbcommon does not distribute a keymap dataset itself, other than for testing purposes. The most common dataset is xkeyboard-config, which is used by all current distributions for their X11 XKB data. More information on xkeyboard-config is available here: https://www.freedesktop.org/wiki/Software/XKeyboardConfig
The dataset for Compose is distributed in libX11, as part of the X locale data.
Relation to X11
See Compatibility notes.
