Use tcmalloc/jemalloc instead of Glibc malloc
Glibc's malloc is not as performant or scalable as tcmalloc, or even jemalloc. You can expect some small to massive performance gains1 by forcing software to use your memory allocator of choice, depending on your workload.
To do this, use your preferred editor to create:
/etc/ld.so.preload
/usr/lib/lib*.so
... where * is either jemalloc, or tcmalloc.
Xorg server
Disable mouse acceleration in X
In order to disable mouse acceleration use your text editor of choice to create:
/etc/X11/xorg.conf.d/50-mouse-acceleration.conf
Section "InputClass"
Identifier "My Mouse"
Option "AccelerationNumerator" "1"
Option "AccelerationDenominator" "1"
Option "AccelerationThreshold" "0"
EndSection
Your config file will take effect the next time you start X.
