Thank you much for your 3 Lines…

Before (ubuntu 11.04, ff 4.0)
1 site – after 10 minutes 200 MB for nothing – hardisk is heavy working for nothing and the heads are very noisy
(today hd dont crash because old, but because useless datatransfer by browsers!!!)

After 3-4 tabs – after 10 minutes less than 100 MB – and the harddisk is silent, after loading ff

I know this post is old but I tried this on Ubuntu 10.04. It works, but since RAM loses all info on shutdown, it’s the same as setting Firefox to clear the caches on each shutdown. For many of us who re-visit the same websites over and over for news etc, the overall effect is to significantly slow things down.

Excellent post! Two questions:

1) Why do you use vm.swappiness=1 ?

My Kubuntu default is 60 (execute ‘sysctl vm.swappiness’ to find out). Lower swappiness seems to favour using RAM in stead of swap so it does make sense there, but this setting of course also influences other programs…

I guess if you have plenty of RAM it’s ok.

2) If tmpfs is 2GiB and not used completely (my ff cache is 14MiB now!), and other applications start to claim memory, can they get into the memory of tmpfs, or do they have to be swapped because I claimed 2GiBs for my tmpfs? (this would suggest performance degradation).

Do your session restores still work after implementing this?

Hi
I’ve implemented this with Ubuntu 9.10.
I can see that there’s now a Firefox cache in the tmp folder.
And I can see how the tmp file is mounted as tmpfs during bootup.
I wonder why more people aren’t using this method?
Maybe in future one of the options in Firefox’s preferences might offer a RAM cache option.
It’s possible to use this method with a RAM-disk in Windows. There’s a youtube video here explaining it.
