no, you don't need to. more ram=less swap used (in an ideal world*) |

If you need more swap, create a swapfile: dd if=/dev/null of=/tmp/swapfile |
| 15 |
bs=whatyoulike, count=howmuchyouwant |
| 16 |
|
| 17 |
mkswap /tmp/swapfile |
| 18 |
|
| 19 |
swapon /tmp/swapfile |
| 20 |
|
| 21 |
tada, a lot of swap, no partitioning needed. |
| 22 |
|
| 23 |
And with 2.6 a swapfile is not slower than a swap-partition. |

Well, until two weeks ago I had 512mb ram and 1gig swap. |
| 29 |
Even light loaded and swappiness down to 10 - after some hours, there are some |
| 30 |
kb in swap, while there is pretty much free memory - and they are always the |
| 31 |
wrong few kb, making everything sluggish. |
| 32 |
|
| 33 |
I bought additional 512mb - and nothing changed, after some hours, a lot of |
| 34 |
ram is free, but linux insistes on putting hundred and something kb into |
| 35 |
swap. |
| 36 |
That is veeeery annoying ;) |
