Adding Swap Space Ram to G1

Today i got a little bored and decided to try to set up some swap space on my sdcard for my g1 to see if i can get a little better running!
I started with formatting some of my card to linux-swap but then i kept running into problems with "invalid argument" commands in the terminal!

So how i actually set it up was i mounted my sdcard as read/write with droidsans and went into my terminal and typed:

dd if=/dev/zero of=/sdcard/swapfile bs=1024 count=(however many mb of swap you want multiplied by 1024 *example* if i want 200mb of swap i would times that by 1024 and then i would type that value right after the count)

it will hang for like 45 seconds and then it will work so be patient then type

mkswap /sdcard/swapfile
then type:
swapon /sdcard/swapfile
then check to see if it worked by typing:
free

*this has sped up my application opening time and when i delete alot of messages it no longer freezes

*use at least double the ram that the phone has for your swap but no more than 2gb

*i have edited my /etc/fstab to try to get it to boot the swap at startup but it doesnt work if any of you want to work with me on that email me at kickfliprock13@yahoo.com
