I don't know, haven't used swapset.
Keep in mind that devs are still trying to find the best settings for using the swap-to-SD solution. The settings from vi_'s comments are recommended for just ramzcache.

Yes, yes it should, that's what I intended.
Could you paste or email me the results of: "sfdisk -lnd" please? - It's probably just a dodgy regex. The bugtracker link is right there on the package listing though...
The reason may be, that before I had made "mkswap" on Linux PC, but now I redid "mkswap" on N900. So there may have been some incompatible parameters before and swapset failed to recognize it.

Hi,
i am testing this with different settings and have question about how to be sure if the lag is due to compache reaching its max size or if the lag is related to a CPU bottleneck.
What i mean is, if i set disksize with 64mb, to reach the max size, i have to load few apps, but if i set the disksize to 96 or 128MB, to reach the max size i have to load more apps.
As i usually use video+psx emulator+youtube when testing 131MB, i wonder if the lag is due to CPU overload.
Because, even if i experience some lags, it is very minimal.
Any advice woudl be very appreciated.
And thanks for this, again, awesome improvement.

Getting the following error in dmesg after certain amount of usage with both 64MB ramzswap and swap on SD enable. Also, happens when using only SD as swap.
Code:
UBIFS error (pid 1022): make_reservation: cannot reserve 392 bytes in jhead 1, error -30

2) Are you quite sure this stops happening when you stop using compcache or µSD?
3) Which way do you start up the use of compcache/µSD now?

It may be related to UBIFS characteristic - remember, UBIFS is very prone to filesystem corruption (basically, undestroyable, at least, when comared to journaling ones), and memory is constantly used for operations on files, before they're written to actual filesystem.
Of course it's just assumption, but I think that patlak might find something useful, to determine why compcache performs so poorly on N900.
