      Description

      The customer is porting their application from Java 8 to Java 11.
      They have noticed a 20 percent drop in performance while engaging with the database.

      JFR lists the hot methods to be - sun.nio.ch.SocketChannelImpl.read(ByteBuffer) and java.net.SocketInputStream.read(byte[], int, int, int)

      Customer also reports no matter which GC(G1GC or ParallelGC), there seems to be a delay when compared to JDK8 ParallelGC
