Naive benchmarks

Singe-threaded (19200x10800) (pre v0.2.0)

./mandelplot -d 19200x10800 -p dark 70.06s user 0.14s system 99% cpu 1:10.24 total

Multi-threaded (19200x10800) (v0.2.0)

./target/release/mandelplot -d 19200x10800 -p dark 85.28s user 8.06s system 258% cpu 36.079 total

1:10 - 0:36 == 0:34 saved

Multi-threaded (19200x10800) (v0.3.0)

./mandelplot -d 19200x10800 87.43s user 10.93s system 349% cpu 28.134 total

Interesting "places"

  • ./mandelplot -z='-0.55,-0.55x-0.5,-0.48' -i 5000
  • ./mandelplot -z='-0.565,-0.565x-0.550,-0.550' -i 10000

TODO:

  • generate image in parallel
  • zooming in
