Hi Listers, Its version 220.127.116.11.0 version of Oracle. We were having a row
by row insert happening and was inserting ~90million rows daily into a
table from Java and the avg response time per row insert was approx
~.4milli second/row insert. We have just converted it to batch insert with
a batch size of ~50 and we observed the response time dropped to~.2
milliseconds/row insert in production. Then we again increased the batch
size to ~80 but this time we are not seeing any further improvements. And
we realized this thing in production because we don't have any performance
environment as such to test it.
So I want to understand from experts, If this is enough to point towards
the fact that we won't get any further improvements if we increase the
batch size further or should we increase it till ~254 , as I read somewhere
, Oracle internally uses batch size of ~254 and so we may get maximum
benefit with batch size of ~254?
