      timestamp_transaction is sometimes in a performance path, and we believe it may perform worse on Graviton ARM processors (see HELP-28951).  We observe that wt_config_gets_def may be called 3 or 4 times for each timestamp_transaction call, and on Intel, it has the majority of performance samples.  It might be better to do a single scan of the configuration string.
