connect to database and recreate tables
insert 10000 rows into the parent table (channelView)
prepare the statements for checking for overlaps and
  inserting to the data table (COND_dummy)
for 10000 insertions {
   make a new iov
   check that the iov does not overlap
   insert the iov and some data
   if we have inserted 100 things, commit a transaction
   if we have inserted 1000 things, report performance
