> This test is running in tier1, and takes about 400 seconds to complete. Thus, > it drags the execution time of tier1 on large machines. The commit includes > changing the sequential run of test cases in > java/util/concurrent/tck/JSR166TestCase.java to the best possible combination > of parallelization to reduce the total runtime of the overall test and > causing least possible change to user and system times. The below comparison > shows existing and newer combinations of parallelizations: > > * before : **200.64s user 20.94s system 204% cpu > 1:48.47 total** > * fully parallel : **308.84s user 23.75s system 479% cpu > 1:09.42 total** > * default-details-tck : **244.69s user 22.03s system 314% cpu 1:24.94 > total** > * default-fjp_details-others : **260.12s user 24.47s system 404% cpu 1:10.31 > total** > > Based on the comparison above, the fourth combination has a result very close > to full parallelization and at the same time having the least deviation of > system and user times among the newer combinations. Hence the commit includes > the changes corresponding to the fourth combination.
