in erlang code, have bitwise operation bor or band . such as: (?srvcc_3gpp_alerting_support bor ?srvcc_3gpp_pre_alerting_support bor ?srvcc_3gpp_mid_call_support) band acc; when system test, find cpu usage higher before. so doubt caused bitwise , not sure. anyone, can tell me cpu usage of bitwise in erlang. how find clue this? unless working on bignums of large size (like 2^2048), operations should hardly measureable compared rest of work program doing.
