On this DSS TPCH test
1.Why is it usefull to sample ?
2.Can the sampling phase be avoided ?
3.Does real test actually start only after msg "Status: Sampling" disappears ?
1.Why is it useful to sample ?
Sampling is just an indication that the test is sending/executing transactions and that the results/statistics during this phase will be stored in the repository.
2.Can the sampling phase be avoided ?
No
3.Does real test actually start only after msg "Status: Sampling" disappears ?
No, the test is executing during the Sampling phase. When Sampling is over the test stops submitting/executing transactions.
