How to improve Script start speed?

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.
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
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)
