What I want: I want to install Ubuntu on a USB pen drive completely independent of the Windows partition schemes, but i want it to run fast.
Ie: When pdrive is not inserted, boot windows and nobody knows i use linux;
when pdrive inserted boot ubuntu(setting the bios to use pdrive when it is present)
||
Problem: because the pen drive is slow Ubuntu loads file/applications to and from the pen drive and/or the swap partition on it.
Only the loading of libraries for active applications (maybe some setting files written once in a while also) make the most semnificative impact on the oss; it seems that swapping (on my 6gb, 4x2.4ghz computer) never takes place(which is good, since pdrive swap is awfully slow). Firefox is extremely slow for example, freezing 5s every 20s if i am installing stuff (which i do everytime i install the os) and 5s every 60s if i am not but have 5tabs open = pain the f*cking neck

My solution:
1 I can use TrueCrypt to make a virtual swap partition(since they do not affect the hdd noone can tell i am using a diferent os) on the windows hdd which would speed up the swapping incredibly much but what about the application loading from the pen drive since hdd swap speed (even with decryption is 10x faster)
2 Thx to blankreg for these commands(though i want to go into more detail about them)
3 Boot to ram
4 Preload is useless with boot to ram

What other ways of optimizing such a configuration?
THX blankreg for this great information,
I would also like to add the PRELOAD package works wonders
