REF : https://bugzilla.tianocore.org/show_bug.cgi?id=4817 Before entering BIOS setup, CoreValidateHandle function executed over 600,000 times during BDS phase on latest 8S server platform. In CoreValidateHandle function, current implementation will go through the doubly-linked list handle database in each call, and this will have big impact on boot performance. The optimization is using Red-black tree to store the EFI handle address when insert each EFI handle into the handle database, and remove the handle from Red-black tree if the handle is removed from the handle database. CoreValidateHandle function changed to go through the Red-black tree. After verification on latest 8S server platform, BDS boot time can save 20s+ after this change.
