...because data access at the outer partitions are faster than those |
26 |
in the middle... |

In the docs on gentoo-wiki (or? somewhere else?) I read that some |
45 |
kind of data are not portable namely databases... |

The normal user like me want 64bit application to access more than |
59 |
2GB per task. |
60 |
In my case: Rendering and simulation takes a LOT of memory |
61 |
especially when it comes to huge counts of vertice or particle |
62 |
interactions. |
63 |
Therefore I plan to install 8GByte RAM. |
