-# Traps
+# Performance
 
-Traps allow you to execute code on various signals. In `pxltrm` I'm using traps to redraw the user interface on window resize. Another use case is cleaning up temporary files on script exit.
+## Disable Unicode
 
-These `trap` lines should be added near the start of your script so any early errors are also caught.
-
-**NOTE:** For a full list of signals, see `trap -l`.
-
-
-## Do something on script exit
+If your script doesn't require unicode, you can disable it for a speed boost. Results may vary but I've seen an improvement in Neofetch and some other smaller programs.
 
 ```shell
-# Clear screen on script exit.
-trap 'printf \\e[2J\\e[H\\e[m' EXIT
-```
-
-## Ignore terminal interrupt (CTRL+C, SIGINT)
-
-```shell
-trap '' INT
-```
-
-## React to window resize.
-
-```shell
-# Call a function on window resize.
-trap 'code_here' SIGWINCH
-```
-
-## Do something before every command.
-
-```shell
-trap 'code_here' DEBUG
-```
-
-## Do something when a shell function or a sourced file finishes executing
-
-```shell
-trap 'code_here' RETURN
+# Disable unicode.
+LC_ALL=C
+LANG=C
 ```
