| 535 | Preload the files listed on the command line into RAM cache so that |
| 536 | subsequent reads on these files will not block on disk I/O. |
| 537 | |
| 538 | This applet just calls the readahead(2) system call on each file. |
| 539 | It is mainly useful in system startup scripts to preload files |
| 540 | or executables before they are used. When used at the right time |
| 541 | (in particular when a CPU bound process is running) it can |
| 542 | significantly speed up system startup. |
| 543 | |
| 544 | As readahead(2) blocks until each file has been read, it is best to |
| 545 | run this applet as a background job. |
