Using a Toshiba Satellite l645d s4025 amd dual core p320 2.1ghz 3gb ddr3 ram 250 gb hdd
Below is the incomplete top report(don't know how to select all to copy) Using an Ubuntu 12.04 amd64 install/live dvd
Recently uninstalled Ubuntu 12.04 due to the fact that the processes(which in most cases there were 4-5 of each process running) were all using close to the same virtual memory listed above. (Possible fork bomb...I was ignorant enough to trust instructions that a later read I shouldn't have(wget http) don't remember the whole string.
I had no issues with performance due to the fact that the processes weren't using much physical ram and were not using any swap. As of now I reformatted the Hdd and have not assigned swap for my Live session.
Is this normal virtual memory usage? Do I need to set disk cache size?(Haven't been able to find much on disk cache) I have read many posts but nearly all are problems with physical memory, swap space(file), or swap partition.

7 users? Is this correct for a live dvd? I believe I only had 2 users: root and my username when running from my hdd before the format.(I could be wrong)

netstat -ap (had to remove too long for the post) shows appx 100 connections mostly stream...and about 7 listening which seems bad to me any help there would be appreciated also.
Only 1 running process(top)? Is it normal for all processes to be sleeping?
I've tried to include as much info as I could(limited on what I am allowed to post), if there is anything else I should check please let me know... I want to reinstall Ubuntu 12.04 any tips would be helpful.
