Hi,
You may want to try jdk8u20.
http://www.oracle.com/technetwork/java/javase/8u20-relnotes-2257729.html
It has changes to improve CompiledScript. Also, you may want to try out
8u40 early access build @ https://jdk8.java.net/download.html
Thanks,
-Sundar

Dear Dev,
I'm using Rhino with JDK1.7u45, which runs really fast.
Each 500 msec, I run 200 Swingworker instances each executing a small
CompiledScript instance with their own SimpleScriptContext.
The scripts are just 5 lines of javascript-code without a loop.
Anyway.
I see a big performance difference with regard to creating a CompiledScript
object and calling eval() on it.
With Rhino it's running immediately at a nice speed.
But with Nashorn, it takes about 15 seconds for the engine to run stable.
Pictures I put here on stackoverflow
http://stackoverflow.com/questions/25811112/can-nashorn-startup-slowness-be-overcome
The startup-lag is not workable for what we use the scripts for.
I would appreciate any insight in using Nashorn more optimal.

On a sidenote, I also tried running Rhino as separate jar In both Java7 and
Java8, as per
https://wiki.openjdk.java.net/display/Nashorn/Using+Rhino+JSR-223+engine+with+JDK8
but the JDK1.7u45 embedded version is still about 160x faster than the one provided in
"rhino1_7R4.zip"
So for Java8, I'm facing some difficulties.
I'm testing with
c:\Program Files (x86)\Java\jdk1.8.0\bin>java -version
java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) Client VM (build 25.0-b70, mixed mode, sharing)
Kind regards,
Roland
