Performance update in Lanai

[Jayathirth Rao]

Hello All,

We have made good progress on Performance related bottlenecks for Lanai implementation under JDK-8228573 <https://bugs.openjdk.java.net/browse/JDK-8228573>.
Updated performance numbers are captured under latest sub-task : JDK-8233190 <https://bugs.openjdk.java.net/browse/JDK-8233190>

@Alexey/Artem : Are we seeing any visible difference in IntelliJ IDE use case with latest change?
Please share your inputs.

Thanks,
Jay
