Tests like this are rarely meaningful. In particular you have a random
number generator in there. They are often built on single threaded code
protected by mutual exclusion. That of itself prevents the code ever going
faster than sequential code, and in fact usually makes it slower due to the
addit
hi,
I wrote a test case to test stream performance,but the parallel sort
always slow than the series sort.I test the data size in : 20,000 ,
5,000,000, 10,000,000 , 20,000,000 .
attatched is the test case source code.
jdk version :
