here continues the description:

Commiting all the 200k together takes 8 minutes; for test purposes I split the transaction in commit size of 500, 1000, up to 200k. The reported times below are those needed to commit all the 200k objects, by commit chuck size:

commit size - seconds 10 48,87 100 17,22 500 15,77 1.000 14,33 5.000 20,43 10.000 26,89 20.000 32,14 30.000 47,53 40.000 55,71 50.000 74,13 75.000 104,52 100.000 163,57 125.000 154,68 150.000 263,94 175.000 277,11 200.000 460,34

I was expecting to get performance degration for increasing commit size, but I feel that commit time increases too quickly. I was expecting that a 200MB commit would take some seconds, not some minutes. Regards, M.Antonelli

One more note: changing the transactial mode from “xa_strict” to “xa” does not change significantly the timings.
