para
A decoder and utility for the Flipnote Studios .ppm animation format.
This implementation is
In a two-hundred-forty-four frame .ppm benchmark running the command
$ para ./benchmark.ppm gif benchmark.gif on a twelve-core,
twenty-four-thread Ryzen 9 processor, para took an average of 566.9893 milliseconds,
while ppm-parser took an average of 50.4171397 seconds.
Running the command $ para ./benchmark.ppm 0 benchmark.png on a twelve-core,
twenty-four-thread Ryzen 9 processor, para took an average of 8.6251 milliseconds,
while ppm-parser took an average of 358.2232 milliseconds.
Rust versus Python isn't very fair, however, this benchmark shows the speed improvements that para brings to the table.
