FWIW
Everything RTALK works on Stephen's 7/11/2012 build. Thank you Stephen.
While generally faster than 7u2 I do have a strangeness in that when my
target is a chain of methodHandles its much slower then when my target
is a methodHandle-callsite-chain of handles. My second case is where I
add
a debugging trap at the start of each chain. Its slower by 4 to 1.
7U2 does not seem to do this.
I would guess the issue is that hot spot optimizes the second but not the
first. Perhaps some inline depth or related limit? Are they any runtime
flags
I should play with? ( tiered compile?)
In summary I am happy with the progress. Currently my fully dynamic
implementation
of Hanoi is about 2x slower than a pure Java version. ( 20% better than
7u2).
thanks to all
mark
