I did comparison between KPv48 and KPv48_Compcache and it seems that RAM and swap usages are both higher with compcache.
What I did: openend microb and did some surfing and monitored Conky. Then left only Conky running and checked RAM and swap after some 5min of idle.
KPv48
RAM: ~170MB
Swap: 90MB
KPv48_Compcache (disksize 98304)
RAM: ~200MB
Swap: 120MB
Wonder why RAM and swap usage is so much higher? I tried to do excatly same things in both cases.
I imagine the 'swap settings for high I/O' or whatever that thread was called has more appropriate swap settings than say swappolube defaults.
Reasoning is swappolube optimises for minimal swapping (hence low swappiness) and the 'high I/O' settings optimise for lots of little swaps.

If we run out of RAM, could this cause lack of responsiveness due to heavy swapping activity? Just trying to understand what is causing quite big loading conditions in my system when using Compcache.

I did the following as root in xterm and got errors
insmod /lib/modules/current/ramzswap.ko disksize_kb=120512 = -1 invalid module format
swapon /dev/ramzswap0 = no such file/dir
Code:
insmod /lib/modules/current/ramzswap.ko disksize_kb=120512 swapon /dev/ramzswap0 swapoff /dev/mmcblk0p3; swapon /dev/mmcblk0p3
swapon /dev/ramzswap0 = no such file/dir

what disksize_kb are you using. Also do you use some speedpatches?

And you are sure speedpatch uninstalls correctly? No remnants? Anyway we are still trying to discover what are the best settings to be used with compcache.
For now you may try (in xterm as root)
echo 20 > /proc/sys/vm/swappiness
echo 2 > /proc/sys/vm/page-cluster
hoping that other vm settings are stock. if that not help then I can bet you have some remnants from some optimization script that have messed your /proc/sys/vm/ (and who knows what else) values. In case lagging continues would you please do cat /proc/sys/vm/* and copy the result here
