massive disk usage/throughput , very slow ( disk killer :( )

[benchonaut]

due to your writing to the TMP_RESULT file and the sqlite writing on each query , with ~200 test objects
there was a 10MB sqlite file ( quit after ~70 hosts) that was fully read and written all the time ( sqlite .. ) so one "cancelled" run
lead to 1Gbyte Disk I/O ..maybe not what you wanted , especially when you can do it in ram 50 times faster..

you already work with for loops , so maybe use it like

TMP_RESULT=""

while foo;do
TMP_RESULT=$(echo "$TMP_RESULT";echo;echo "APPEND THIS LINE TO RESULT")
done
