1. I got 4G ram installed on my IBM X61 Laptop, with Ubuntu 9.04 Jaunty Desktop for i386 installed.
2. I need to use my whole 4G of ram bcoz I always has about 400 tabs opened in my Firefox.

All 32bit system can allocat only 33.5G of memory.

X61 uses Intel chips and VGA chip, which is some kind of shit.
Want to improve the xorg's intel driver, you got to install the latest kernel and driver, with UXA mode enabled.
Then, you might get glxgear score about 700~800fps, nice.

Now here comes the problem.

sockstat was only for freebsd, now it's on linux too. something like ‘lsof -i -n’ or ‘netstat -anpe‘.

You can get the 0.3-1ubuntu1 version at the "Builds": https://launchpad.net/ubuntu/+source/sockstat/0.3-1ubuntu1

I download it and install it on my jaunty i386 without any problem.
