Hi Miguito!

Unfortunately I do not think it is possible to tell Firebird that
certain operations should have low priority. However, if it takes one
hour to update and insert 100000 records, then that may indicate that
something could be improved. It is possible to insert several thousand
records per second, though lots of things may reduce the possible
speed (if your 100000 records contained high-quality images and you
had to transfer the images to Firebird over a slow telephone line,
then even ten hours for 100000 records could be impossible).

So, my recommendation would be to change your program to use a DSQL
for inserting/updating, prepare it once, loop through your records and
commit for every 10000 inserts or so. Also, please check that you do
not have any indexes defined with lots of duplicate entries.

HTH,
