First expression is very positive

After short usage, I would say that device is a bit more responsive (my subjective judgement) under heavy load (multiple application running simultaneously).

Thanks for bringing this option to Maemo!

EDIT: After some usage I see problems, device start to lag and eventually does not respond at all, need a reboot.

Hopefully it will make the N900 more responsive or more likely it would take it more time to start lagging. The worst thing that could happen would be frequent random reboots. However a reflash will solve anything. If you are afraid to try it first backup using backupmenu and then try the patch.

So far I am not seeing much difference to be honest..although it hasn't been long.

Make sure your compcache swap has higher priority than internal flash swap i.e. when cat /proc/swaps ramzswap has higher priority value than mmcblk0p3

Higher priority value meaning closer to zero I guess?
Ramzswap0 was filled first after reboot, so that looks okay.

Curious to see how it's going to behave in terms of cpu/battery costs and performance wise after a period of time...

Code:

cat /proc/swaps
Filename                                Type            Size    Used    Priority
/dev/mmcblk0p3                          partition       786424  57804   -2
/dev/ramzswap0                          partition       131064  130728  -1

I am installing right now..
should we be more careful with compcache enabled about swappiness value? a value of 100 would make the cpu compressing data all the time?
edit: installed with priorities correct!. testing begins..

and how can we do that ?

disable and enable again "regular" swap - as one turned on later, it will have lesser priority.

Another approach is to get swqapon from - for example - debian - it have setting priority ( - p ) working, unlike vanilla maemo swapon.
