Swap partition not writing pass 2.5MB

[aaa12345]

I got my swap partition set up but seems like the router doesn't want to utilize it pass 2.5MB...does anyone else have the same problem?...is it because I still have some free RAM left? Below is the output from the free command (it almost always look like that).

I'm using Merlin 374.39 on rt-n66.

             total         used         free       shared      buffers
Mem:        239712       179184        60528            0           60
-/+ buffers:             179124        60588
Swap:       250516         2356       248160

Yes, why use the swap space when there is free RAM?

Swap space will be used when needed, not when not needed

I'm using Transmission to do torrent and it's taking a lot of RAM, that's why I added the swap at first but it does seem like my free RAM doesn't drop below 60MB (only the buffers drop), so I guess it's normal?

Yes, linux kernel will use free RAM as buffers to speed things up. So your "free" RAM really is free+buffers.
