+## The following variables can be customized at build time. Use env or export to change at your wish
+##
+##   Example: env _microarchitecture=25 use_numa=n use_tracers=n use_pds=n makepkg -sc
+##
+## Look inside 'choose-gcc-optimization.sh' to choose your microarchitecture
+## Valid numbers between: 0 to 25
+## Default is: 0 => generic
+## Good option if your package is for one machine: 22 => native
+_microarchitecture=0
+##
+## Disable NUMA since most users do not have multiple processors. Breaks CUDA/NvEnc.
+## Archlinux and Xanmod enable it by default.
+## Set variable "use_numa" to: n to disable (possibly increase performance)
+##                             y to enable  (stock default)
+if [ -z ${use_numa+x} ]; then
+  use_numa=y
+fi
+##
+## For performance you can disable FUNCTION_TRACER/GRAPH_TRACER. Limits debugging and analyzing of the kernel.
+## Stock Archlinux and Xanmod have this enabled. 
+## Set variable "use_tracers" to: n to disable (possibly increase performance)
+##                                y to enable  (stock default)
+if [ -z ${use_tracers+x} ]; then
+  use_tracers=y

+##
+## Enable PDS CPU scheduler by default https://gitlab.com/alfredchen/linux-pds
+## Set variable "use_pds" to: n to disable (stock Xanmod)
+##                            y to enable
