Do you send tons of literal commands like
insert into tbl(f1,f2) values (1,2);
or do you prepare an insert statement with parameters
insert into tbl(f1, f2) values(?, ?);
and keep feeding parameters and executing the prepared statement? The first
way is very slow on massive operations, because each command is parsed,
compiled, prepared, executed and discarded.
