In the /etc/init.d/metalayer-crawler0, as root replace line:
     dsmetool -f "$DAEMON -F" -U $USER
with something like:
     dsmetool -n 19 -f "$DAEMON -F" -U $USER
and then run:
   /etc/init.d/metalayer-crawler0 stop
   /etc/init.d/metalayer-crawler0 start
This should be fairly safe change as dsmetool will just stop
restarting crawler if it will obstinately refuse to start. :-)

Yikes... Could you verify this with a stopwatch (when you're waiting
for something, the timespan may feel longer)?

I would be interested how many and of what types of files you have
on your device.  Could you run script like at the bottom on your
MMC (on device this would be "./filetypes.sh /media/mmc1/") and
mail the results?

	- Eero
# count how many files of each type are on the device.
# the filenames are saved under each type into "file-type" dir.
if [ $# -ne 1 ]; then
         echo "usage: $0 <dir>"
         echo "counts how many files and of what type are under given dir"
         exit 1
if [ \! -d $dir ]; then
         echo "dir $dir doesn't exist!"
         exit 1
rm -rf file-type
mkdir file-type
cd file-type
for file in $(find $dir -type f); do
         if [ "$ftype" != "$file" ]; then
                 echo "$file" >> $ftype
                 echo "$file" >> _notype
for ftype in *; do
         wc -l $ftype
