Lock Contention is high in GCC/Clang for Postgres

PostgreSQL
1

PostgreSQL version: 13.3
Operating system: RHEL8.4
Description: Lock Contention is high in GCC/Clang

Example Perf data for 24vu(TPCC)

14.99% postgres postgres [.] LWLockAcquire
7.09% postgres postgres [.] _bt_compare
8.66% postgres postgres [.] LWLockRelease
2.28% postgres postgres [.] GetSnapshotData
2.25% postgres postgres [.] hash_search_with_hash_value
2.11% postgres postgres [.] XLogInsertRecord
1.98% postgres postgres [.] PinBuffer

LWLockAcquire(Lock contention) is high in GCC/Clang while running TPCC(HammerDB bench environment)
Is there a way to tune the lock contention?
Any recommendations to tune/reduce the lock contention?
