Hi,
can I have a review of this performance improvement to
java.time.Period#parse and java.time.Duration#parse?
bug: https://bugs.openjdk.java.net/browse/JDK-8055004
webrev: http://cr.openjdk.java.net/~redestad/8055004/webrev.0
The patch avoids String allocation through matcher.group(n) calls,
utilizes recently added
capability of parsing CharSequence offsets and improves on the rather
awkward way fractions of a second
was aligned to nanosecond precision in java.time.Duration.
Microbenchmarks show a 1.2-1.5x throughput improvement in both cases.
Thanks!
