It depends. Actions on large files, especially deleting or truncating |
| 14 |
them, is much faster now (nearly instantly where it was several seconds |
| 15 |
with ext3). Overall performance "feels good" but it of course cannot |
| 16 |
overcome the limits of an HDD. |

Conversion is fine. It will start using extents (the main advantage) for |
| 23 |
new files. I don't know what it does for new allocations to old files. |

Raid-1 does not need any attention (IMHO) but you should apply some |
| 33 |
tweaking to Raid-0. However, that is also true to Ext3 and the |
| 34 |
parameters should not have changed. So the setup can stay the same. |

Hope this helps, |
