Hi Jochen,
I am still thinking about how to improve indy performance further in
the method overload cases, e.g.
```
def same(String obj) { return obj }
def same(int obj) { return obj }
def same(float obj) { return obj }
for (int i = 0; i < 100000; i++) {
[1, 1.0f, '1.0'].each { same(it) }
}
```
If we cache both receiver type and argument types, I find the
performance of this case can be improved a lot, but other cases performance
is reduced quite a bit too... so I am trying 2 levels cache: the 1st level
cache is the current cache for receiver type, its size is fixed as 16 by
default, and I want to add 2nd level cache is for caching argument types,
its size will be fixed as 16 by default too. The 2 caches are seperated, so
receiver types kept in 1st level cache will not be cleared, and 2nd level
cache can provide more hot candidates for better performance.
Cheers,
