Just for notes, I have 2Gbs of ram. I have ~1Gb of swap. I don't think |
19 |
I have ever seen it use over 100Mbs or so of swap since I built this |
20 |
thing. Most of this depends on the programs you are using. If they use |
21 |
more memory than you have, you need more swap. If not, then maybe not. ;-) |

If you only want it to use swap when really needed, set it like this or |
24 |
something close: |
25 |
|
26 |
root@smoker-new / # cat /proc/sys/vm/swappiness |
27 |
20 |
28 |
root@smoker-new / # |
29 |
|

The lower the number, the more it tries not to use swap. The higher the |
31 |
number, the more it will try to use swap. Since I rarely use more than |
32 |
1Gb, compiling OOo may be a exception, I set mine to 20. My drives are |
33 |
the old IDE and are not as fast as the new SATA drives. Use echo to |
34 |
change that setting just in case you don't know already. |

Hope that little bit of info helps. This is one of those "it depends" |
37 |
situations. No matter what you set it up for, you will want to change |
38 |
it later. :-) |
