Chetan Sarva chetan

Keybase proof

I hereby claim:

I am chetan on github.
I am chetan (https://keybase.io/chetan) on keybase.
I have a public key whose fingerprint is 0CC2 6FA5 8102 1C53 1774 A3F4 F585 739B 124A CC0F

To claim this, I am signing this object:

tl;dr: xz offers much better compression but at the expense of far slower (de)compress speed. we should probably switch to gz (or some other codec offering a better balance of compression/decompression speeds), but it's hard to confirm the overall improvement without first rebuilding world.

Reference benchmark

Tested below packages by running hab pkg install core/<pkg> inside a studio and then tarring up the contents of /hab/pkgs/core/<pkg>

List of Isolators

Side note: all available resource metrics are documented here:

Filesystem Isolators

These are used for isolating files on disk from both the host system as well as other running tasks.
