Funny, I posted somehow related thread on memory consumption a way back (don't have the time to look it up).

I also noticed phone lagging VERY much once RAM is 100% full (and swap is necessary). This makes sense as flash is slow(seems to be especially slow on N9 but that is my own opinion).

Bit off-topic, but the performance of N9's flash storage seems to vary quite wildly from N9 to another, Maybe Nokia aquired chips from several sources.
For example I have two N9's which give very different results using hdparm.:
Rev. 1603 Serial: 5093798
Code:
~ # for i in {1 2 3}; do hdparm -tT /dev/mmcblk0 2>/dev/null; done
/dev/mmcblk0:
Timing buffer-cache reads: 280 MB in 0.51 seconds = 561679 kB/s
Timing buffered disk reads: 94 MB in 3.00 seconds = 32071 kB/s
/dev/mmcblk0:
Timing buffer-cache reads: 280 MB in 0.50 seconds = 562285 kB/s
Timing buffered disk reads: 95 MB in 3.02 seconds = 32176 kB/s
/dev/mmcblk0:
Timing buffer-cache reads: 302 MB in 0.51 seconds = 604549 kB/s
Timing buffered disk reads: 95 MB in 3.02 seconds = 32137 kB/s
Code:
~ # for i in {1 2 3}; do hdparm -tT /dev/mmcblk0 2>/dev/null; done
/dev/mmcblk0:
Timing buffer-cache reads: 138 MB in 0.51 seconds = 276993 kB/s
Timing buffered disk reads: 80 MB in 3.00 seconds = 27297 kB/s
/dev/mmcblk0:
Timing buffer-cache reads: 144 MB in 0.51 seconds = 288364 kB/s
Timing buffered disk reads: 79 MB in 3.02 seconds = 26757 kB/s
/dev/mmcblk0:
Timing buffer-cache reads: 152 MB in 0.51 seconds = 305113 kB/s
Timing buffered disk reads: 81 MB in 3.01 seconds = 27466 kB/s

okay it was difficult to maneuver but i managed to copy top's output from landscape mode.
edit
and here's the output for free.
p.s. i'm not sure if y'all appreciate the severity and extent of my computer illiteracy. i don't understand more than 5% of what anyone is saying. on the other hand you can see that i am capable of following instructions. still i understand if i have exceeded the supply of patience and tolerance for newbie ignorance available within the relatively advanced community of TMO.

it just cuts them off. lol. but in landscape you can get pretty much the whole line. probably not the best solution especially if you want to be on your desktop.

I've installed fasterN9 and still suffering tons of lag especially playing urban fat burner. are there any other easy methods of speeding up the phone?

You could try using DropCache from the ovi store. It seems to help me and speed my N9 up if it's been busy for a while.

@Jeffery04
hey that actually worked pretty well. i can actually play urban fat burners now. but like you said it isn't a real remedy for whatever is lagging out the memory. but at least now I'll be able to achieve my anti junk food trophy
@AndyNokia232
picked up and used the app and here are the results:
definitely freed up some memory. edit: it would be nice to be able to increase my total amount of swap available.

There was an article on everythingn9 at some point last month I think (about swap)

RAM should be in use so that's normal, question is how much of it is used as cache and thus reallocated when some application needs it. Running "free" from the command line would be more informative.
~ $ free -m total used free shared buffers Mem: 985 760 224 0 17 -/+ buffers: 743 241 Swap: 412 94 317@Yisroel.
Your top output seems to be cropped from the right side so names of the processes aren't shown. Try to print out something like this:
