Ok, swapolube optimisations removed set to stock values.
Speedpatch removed.
Still lagging a bit once cache is full.
Since I'm not exactly knowledgable on this are there any more values I need to correct?

Code:
$ cat /proc/swaps Filename Type Size Used Priority /dev/ramzswap0 partition 120504 120492 -1 /dev/mmcblk0p3 partition 786424 63204 -2 ~ $ cat /proc/sys/vm/* 0 10 500 40 500 0 0 59326 30000 30001 30002 30003 0 0 0 0 45 32768 201135 -66 98304 -121 131072 1024 32 0 65536 2039 4096 2 0 0 0 50 2 0 0 20 100

I've also got a bit tuned syspart (/usr/share/policy/etc/rx51/syspart.conf)
looking forward getting memory free fully working as it's a big stopper at the moment IMO.
Re memory free - it is working OK, trust me on that. My understanding is that what happens is the best possible scenario, i.e. instead of notification for a page that was just marked as unused it is immediately overwritten. While we have notifications for the pages that are not immediately overwritten.
For sure there are optimizations to be done, if you look at the code there is a mutex used on write operations.
And for the amount of applications you are testing with - try that on your laptop and tell me how it went

Responsiveness MUCH improved with page-cluster set to 0 and swappiness set to 10

@TMavica - and do you thing there is an improvement on responsiveness, or things are just the same?

Intrigued as to how phone-ui is with this added. I'm in the middle of a prepping a reflash to end all reflashes of my phone. Off topic, but so far, the best "feel" gains have been eMMC fully ext3 and swap only on SD card (things like Fapman zip along and I can fuddle with the phone doing other stuff while it's doing it's thing) but the phone-ui still remains a stuttering mess.
Either way, will give this a shot later after work, unless someone has beaten me too it.

@gregoranderson - I would recommend to wait before trying it a little bit, today I will try to make optimizations to the way swap read/write/free requests are handled, at this point compcache does not bring much improvement, while could lead to laggy system from time to time. The "testing" so far was to prove that it is working at all, without oops and hangs.

OK guys, my conclusions so far:
1 - compcache works
2 - Anything above (lets's say) 64-96 MBs for disksize_kb results in a massive swap trashing at some point in time. Yesterday it was the first time for maybe an year I missed a call because the UI was stuck (because of the swap trashing)
3 - using the above size should not harm , only can improve things, but no wonders. I setup my primary phone that way, so will see how it will progress with time.
4- The only viable option so far to get rid of the UI lag is to move swap on SD card. Even if it is class 2 you forget about lagging.
I don't think I can do much more on that, sorry.
