Spotters Badge for vi_ ; that'll save me the hassle of trying to thrash one together myself.

...and I just thought I'd pop in to let folks know it existed....can't have any secrets around here it seems :)

...not sure what the best way to approach the tunable settings is though. Perhaps a config file, perhaps gconf, perhaps just having people edit the script. I'm somewhat undecided....

Anyways, it lives here.

..oh, an in the interests of full disclosure, I did actually start with gregoranderson's initial script and missed the rest of the conversation from that point on ;)

I am using it, so far so good.

...I've not made it particularly clear, but once you install it you will need to reboot for the startup event to trigger. You can mount and unmount the SD swap at any time though. Might add a compache option...but I was wary of messing up the installation databases as people were reporting that insmod'ing the module was causing reboots.

...speaking of which, I guess I could add some reboot/failure tracking to prevent boot loops easily enough....might do that next actually.

swapon /dev/ramzswap0
swapoff /dev/mmcblk1p2; swapon /dev/mmcblk1p2
(I use my sdcard for swap)

So, after a short period of contemplation I went with:

Code:
swapoff /dev/mmcblk1p2
insmod /lib/modules/current/ramzswap.ko disksize_kb=65536
swapon /dev/ramzswap0
swapon /dev/mmcblk1p2
And everything is groovy again. The old N900 is snappier than a crocodile who's found himself at a penguin parade.
I tried compcache using this method, and it seems to work. But it made the device significantly slower as far as I could see.
Do any of you have better experiences?

I am on cssu &kp49, swap on microsd, no speed/battery patches.

Thanks, that seems to have been it.

On my test N900 with a SD card, it was very, very quick with both compcache and SD.

On my live phone without a SD, it seems very sluggish when first turned on with compcache, but settles down after 5-10 minutes.

Comp-cache, 65mb file size causes me sudden unexpected reboots, its out of my my tolerable range (which is approx 1 unexpected reboot a month :d ), now using SD swap only ,, same result with SwapSet.

Installed and works very nicely indeed. Cheers for putting in the effort.

(KP49 / CSSU Testing / swap on SD for the curious)
