        Description

        We are seeing a 30% performance regression in Mustang b90 with the server compiler.

        We are still narrowing down the source of the regression (so consider this an "early warning system"), though the performance regression does not come from GC (GC times are the same between builds), nor the JDK (the b89 libjvm with the b90 JDK performs as expected).
