I have the compression set to lz4, which doesn't compress a lot but does compress/decompress with minimal CPU overhead so I feel like I'm getting some benefit from it. In general compression can "speed up" disk operations since you can write easily compressible data faster than regular data. Other than that after boot-up I run 'sudo chattr +C /tmp' to make my /tmp dir not copy-on-write, which helps with building packages. I also have a daily cron job to balance my disk and to scrub it. Overall I don't really use very many features that aren't available on ext4. --=20 Efraim Flashner =D7=90=D7=A4=D7=A8=D7=99=D7=9D = =D7=A4=D7=9C=D7=A9=D7=A0=D7=A8 GPG key =3D A28B F40C 3E55 1372 662D 14F7 41AA E7DC CA3D 8351 Confidentiality cannot be guaranteed on emails sent or received unencrypted --mvpLiMfbWzRoNl4x Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEoov0DD5VE3JmLRT3Qarn3Mo9g1EFAl2UV4YACgkQQarn3Mo9 g1GacRAAuk3X07TZaFvbUZTHptIpgrCezl1Xd0C8RYowuT76+8cxA26fxMTAQjTN JfGd+jox+IbLJcngA0VS/Gl+GuR5Z3T3jRaMsD/EwuBd7gFc0WmJDV4IeDs6OAzN 0cG/UFI6O3me2y134n1xkO1D0hC6EAQMLLbvdot3D1VyOx880I5G8qrP4lbq6jkE 94TSkHxhYAtNC7Ndo2n3ATNKdYHT9TM0qijnNTnZTA40N8z0v2h6Efg/NslJiJV0 eieX3emSQRP8g+/gaIC8KlpxYCRsSD4Zr7mz6e7trEdJa5W4OaTa19xWMGK+n9Eq aTXDXZFFZYHCzi+QSyIOWCbiy69Q8x6KE1/sZRPNnEfhFCuzip6zMz4JiHs9ToL6 GkfFXN8lz2IAJIWYJWp10wcVmolWHO9SLOtaeebeV+QPPPL37w9TOqhrERV64jLT UCFzywtvGM8wSRN16ChRBw9oyWX2EOEUw2hrITo76NCymqiobMOVowkmeV2jhLBb Gt7oLM8jBtso/knZT1qWbLbOegrCG/o33C9dEvEZuCUlQQAkMS3byqPqBK1MFkPI e0rtQaPFZ2Qnole7ufcQm3Rz9PPQUc7IBIOwOvatRBYSp9QH/DzuMjO/ePzmlaYi WNgXeTObt6sdz679b/sNm8ehmu4fW+KSspS3XbOBU2DqTZNU+tA= =QFAF -----END PGP SIGNATURE----- --mvpLiMfbWzRoNl4x--
