Thanks.

Even I do not really see the necessity. I do in no way want to criticize your work, but:
We have 1G of mem, from which 256M is reserved for ramzwap (swap usage). So if you not have heavily modded your device, lots of daemons running and/or tons of apps open at the same time, this should not make the device any faster.
And I do not know of any problems with swap fragmentation (as on te N900, need to defrag/re-swap).

Out of curiosity: where do you gain the additional swap space from? Increasing ramzwap (hereby decreasing real RAM) would not make sense. Or from "unused" mtd5? In latter case you should give a hint/warning (at least to 'old-style' ubiboot users) about using that device.

I often have situations, then I have about 50 mb RAM and ~400 mb (from 768) of SWAP free... With 255 mb SWAP my device works slower than with 768 mb...

Additional space - from rootfs.

Code:

dd if=/dev/zero of=myswapfile bs=1M count=513

So, I think, old-ubiboot users can sleep quietly...

Thank you for this. I am excited to see if there is any performance increase.

I use Drop Cache, and in that program it still has the SWAP listed at a maximum of 255mb available. I'm assuming that has more to do with the app than an actual reading of available SWAP. How to I check available swap from the command line, since my usual way is not giving a proper reading?

Code:

cat /proc/swaps

afair DropCache does only similar thing as swap defragmentation. So possibly it just drops ramzwap, not any swap files/devices/partitions. Most probably, as DropCache did not know about Swap Management

/dev/ramzswap0      partition    262136       0        -1

Not sure that was what I was looking for...

It seems to tell me the same thing Drop Cache told me.

Then what?

The output states that you have 256M of swap (ramzwap). Stock configuration.

I do not know the details, but if ancelad created a swap file it should show up here. (assuming you installed swap management)
