use systat
Using 'systat -iostat' it shows mostly idle with 25-70 MB/s on the aacd0
array. Most of time above 50. Thanks for the help!

70MB/s can't be "mostly idle". or you meant CPU mostly idle.
changing to RAID-not5 will help. seeking why disk traffic is so high -
will help eve

That was my whole point of showing you the low usage. I take that as a
yes, RAID 1+0 would provide a dramatic difference in speed, thanks!
the only adventage of RAID-5 is less "wasted" space than RAID-1. one and
the only adventage. write performa

That was my whole
After reading tuning, it suggests the SWAP should be double RAM.
According to dmesg...
installing database on RAID-5 or asking if to add swap (when almost none
is used)? what is more stupid? whould we vote?

we have 3GB of RAM available with actually 4GB physical RAM installed?
If you're using a 32-bit (i386) kernel you need PAE. Or switch to 64-bit
(amd64).

Adding swap is unlikely to help you, as you're not really using mu
wap: 2048M Total, 164K Used, 2048M Free
I also have assumed in the past that db performance could be better if I
get off the system RAID-5 and put it on 1+0? The system has 4 SATA
drives.
