Thanks.. I'll check em out.

I actually don't have the original values anymore..

They were quite different, though. If anyone wants to check, just run this (root not required):

Code:

echo -n "dirty_ratio: " ; cat /proc/sys/vm/dirty_ratio
echo -n "dirty_background_ratio: " ; cat /proc/sys/vm/dirty_background_ratio
echo -n "dirty_writeback_centisecs: " ; cat /proc/sys/vm/dirty_writeback_centisecs 
echo -n "dirty_expire_centisecs: " ; cat /proc/sys/vm/dirty_expire_centisecs 
echo -n "min_free_kbytes: " ; cat /proc/sys/vm/min_free_kbytes 
echo -n "swappiness: " ; cat /proc/sys/vm/swappiness 
echo -n "vfs_cache_pressure: " ; cat /proc/sys/vm/vfs_cache_pressure 
echo -n "onboard_nr_requests: " ; cat /sys/block/mmcblk0/queue/nr_requests
echo -n "sd_nr_requests: " ; cat /sys/block/mmcblk1/queue/nr_requests
