Hi, this looks good.
Testing cold[1] startup on my machine I see an improvement ranging from around 30-40ms on a minimal test to around 60-80ms on a larger app. Warm startup and footprint measures seem largely unaffected, as would be expected.
I also did an experiment with allowing secondary ordering in the plugin so that java.base could be ordered directly after the classlist-ordered resources but impact got lost in the noise, so it doesn't seem worthwhile to complicate things further.
Thanks! /Claes [1] simulated by calling echo 3 > /proc/sys/vm/drop_caches between runs On 2016-05-09 19:41, Jim Laskey (Oracle) wrote:
