I would like to use openmosix for my class network.. |
| 2 |
16 gentoo's, now running the latest gentoo-sources.. |
| 3 |
Is overall performance improved when you use openmosix? |
| 4 |
Like for desktops and such (i noticed preempt isn't in it..) |
| 5 |
And if so, any good tutorials out there? |
| 6 |

Thanks! |

|| Correct me if I'm wrong, but IIRC, the original mosix was useless for |

| 44 |
