I'm seeing this consistently between my N900 and 2 others. Device is snappy for the first day of use, then the swap usage gradually increases and the device really starts to slow down over the course of a few days as the swap usage gets higher and higher.

I found it quite amazing that the device is already 50MB into swap when initially powered up. Having owned an N800 and N810 (which had 128MB real memory, and were able to run swapless) I found this very surprising. I wonder what has blown the memory usage out so far for it to need swap with absolutely no apps running.

I wonder if there are some features and daemons we could safely disable to reduce the memory usage and turn the swapfile off? This would permanently fix the "device runs sluggish" problem. If any process has a memory leak, it will get OOMed (killed by the kernel for using too much memory) and we'll be able to identify it a lot easier.

Thoughts, anyone?
