A wrinkle with using the local content http filter database

William Warren
Astaro has hte kernel swappiness set to 60.  I ahve 2 gigs of ram in my machine and as per the following thread I am using hte mem option:
https://community.sophos.com/products/unified-threat-management/astaroorg/f/55/t/44899

However since my ram usage stays below 40% there's no reason for the box to touch swap.  It turns out the default swappiness of the 2.6 linux kernel is 60.  This means the machine is more likely to keep files cached in ram and nOT evacuate them to disk when needed.  The swappiness value should be reduced to zero..here's how:

login as root to the box
joe /etc/sysctl.conf
at the bottom type vm.swappiness=0
ctrl-k x
reboot the box.

    Actually after looking at the Hardware reporting, the Mem is always at ~33%. and the swap is always at 0%..

    I guess there is no reason for using the tweak?

    if you aren't swapping you don't HAVE to...however it's a good preventative measure..it's an option like all of my tips are..[:)]
