I've set up a script that does some sanity checks -- plugged in? charging? locked? 3 AM? and will "re" swap out of internal, onto external and back onto the internal in order to clear out.
Thanks for the script but I'm talking about my settings ( and my tools ). I know about pci-interface and bus and that concurrent interface when connecting more then 1 harddisk to the computer. If u have read my posts in this thread I use a readahead of 16 and nr_requests < 4. I've tested nightifire setting with swappoff /dev/mmcblk0k3. I think the priority for SD remains the same ( -1 ) but it is much slower. I didn't tried his swapon-tool because it didn't work on my device. This is something I can test again and setting prio to 1 like nightfire suggest but right now my setting with the 2 swap-space is much faster. I think it is a bug or my tool is crap but I don't think so.
