Swap or compcache or both or none

[metalspring]

Hopefully one of the mods can turn this into a poll but I've been curious as to what everyone uses and why. So do you use compcache, swap, both or none of them and why do you use (or not use) them and why.

Personally I usually use swap because it always seems to lag much less than compcache and it fills up much more slowly allowing me to not worry about clearing it very often

None. Seemed like my phone eventually slowed down with either, so I gave up using them.

I've been using a swap partition for about 6 months now. Seems like that was the only way for my phone to run any gingerbread ROM. Have been using winner00s cm7 builds about as long. Would like some script or somethin so I don't have to use swapper2. I remember there was a thread awhile ago I was talking with somebody I think kevdog about it but have No idea where it would be at. But yea I use a 64mb swap partition with swapper2.

There is a way without swapper2. Run this in terminal emulator or copy/paste it into any script in /etc/init.d (if you have an init.d folder) or use script manager to make a script with this in it and run it at boot

swapon /dev/block/mmcblk0p3
and to turn it off
swapoff /dev/block/mmcblk0p3

Btw I pulled that from swapper2 itself lol under advanced settings it says the default directory for the swap partition and I found the swapon and swapoff scripts from running busybox in terminal to show all available commands

Yea I sometimes had to use that when I was having trouble with swapper2. Thanks again for that tho, it's a very useful command. And Yea I do have a /etc/unit.d/ folder, I'm on cm7. Now how do you go about setting swappiness? In the /etc/sysctl.conf file?
Was it you that listed all those sysctl commands in a different thread? I take it that's the same file those are related to? So I could just set swappiness to like 5 or 10 and I'd be all set? Tons of questions I know. Then I could check if it's working by looking in the memory section of SetCPU.

Several ways to set swappiness
1. Add this into the sysctl.config file
vm.swappiness = 30
2. Add this at the end of the first script in init.d
sysctl -w vm.swappiness = 30
3. Run this in terminal emulator (not sure this way sticks though)
sysctl -w vm.swappiness=30
Btw keep all spacing the same

What about all those other values you were talking mixing and matching in the sysctl thread I can still use those right? Thanks again

By the way I've been running swappiness at 5 so it takes longer to fill up or whatever. Or is that too low?

Yeah you can use all of those and as for 5 being too low it all depends on your usage. Just run everything for a day or so like you'd normally do without rebooting then type in
free
in terminal emulator and if you still have tons of swap space left then you can increase it

Hey metalspring thanks for all your help man. I've been running without swapper2 and just that swapon command, but how does it manage itself? In other words does it know to restart once the majority of free swap memory is used up?

I've also been running all those sysctl tweaks you posted so the swappiness is set at 30, or does that not even effect swap??
