A very fast cat implementation, even faster than fcat
Here a little benchmark of how fast it can pipe a file to /dev/null:
program file.txt > /dev/null with program ∈ {cat, fcat, flaschencat}
| 1 GB File | 5 GB File | |
|---|---|---|
| cat | 79.6 ms | 468.2 ms |
| fcat | 57.1 ms | 265.2 ms |
| flaschencat | 38.6 ms | 195.4 ms |
Here another benchmark of how fast it can pipe a file through itself and then to /dev/null:
program file.txt | program > /dev/null with program ∈ {cat, fcat, flaschencat}
| 1GB File | 5 GB File | |
|---|---|---|
| cat | 305.1 ms | 1.559 s |
| fcat | 74.8 ms | 324.5 ms |
| flaschencat | 57.0 ms | 199.3 ms |
