Memory map the metadata blobs instead of doing IO syscalls #76

Closed ariel-miculas closed 1 year ago

ariel-miculas commented 1 year ago

For a 658M rootfs, traversing the mounted filesystem with tree using a release build: target/release/puzzlefs mount -f /tmp/oci-barehost test /tmp/puzzle

Before memory mapping: 2325 directories, 19265 files tree /tmp/puzzle 0.10s user 0.40s system 0% cpu 50.361 total

After memory mapping: 2325 directories, 19265 files tree /tmp/puzzle 0.07s user 0.17s system 14% cpu 1.701 total

Fixes #19
