danielsun1106 edited a comment on issue #1135: GROOVY-8298: Slow Performance Caused by Invoke Dynamic URL: https://github.com/apache/groovy/pull/1135#issuecomment-570983832 Here is an edge case: we set `groovy.indy.optimize.threshold` to `0` at first, so the target of callsite `toString` will be set because the threshold(`0`) reaches. The newly set target is not good for polymorfic calls(the subsequent calls when `i >= 10`), so when fallback count reaches threshold, we will reset to the `fromCache` target, i.e. the default target. ```groovy for (int i = 0; i < 1_000_000; i++) { [1, 2.0f, '3.0'].each { if (1 != it && i < 10) return it.toString() } } ``` (indy2(after d799d22, `groovy.indy.optimize.threshold`: `0`): **3s**; indy2(before d799d22, `groovy.indy.optimize.threshold`: `0`): **12s**; indy1: **27s**; CS: **4s**; on my another machine)
