Hi,
please review this change that moves the use of SALT to iterator
creation, which would allow for certain startup
optimizations in the future.
Bug: https://bugs.openjdk.java.net/browse/JDK-8201650
Webrev: http://cr.openjdk.java.net/~redestad/8201650/open.00/
This does make the randomness of iteration order weaker as we're only
randomizing the starting point (varying with
the size of the collection) and the iteration direction (run-to-run
variant; weaker than calculating per size, but
allows this patch to be performance neutral).
Some Set/Map operations become very slightly faster with this patch, but
that's in the noise. Iterator operations
remain largely performance neutral, sometimes even a bit faster.
Thanks!
