Jochen Theodorou updated GROOVY-11842:
--------------------------------------
Description:
As can be seen in the IndyInterfaceUsageTest there is a stack trace element
showing IndyInterface. This is bad for inlining and general performance.
!improved_indy.svg!
of course a programm like
{code:Java}
int foo(){1}
int a
for (int i=0; i<MAX; i++) {
a = foo()
}
{code}
is not much of a test for anything. It was supposed to show better inlining,
but unlike Groovy 3 all later Groovy version fail to unroll the loop and
eliminate the assignment to a for later executions. The graph though shows that
the branch performance is better than Groov 3 or 4. Not only in the long run,
but also on start.
