From 34e019dc29044e6f3b8d256a20f4ca83a3ac24a7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B6rn=20Gustavsson?= Date: Wed, 27 May 2015 04:21:20 +0200 Subject: Clean up rpc_SUITE:call_benchmark/1 The call_benchmark/1 test case is supposed to return a comment about the number of RPC calls per second, but the return value from the function that produces the comment (do_call_benchmark/4) is ignored. The test case is essentially useless except as a smoke test. Simplify the test case and correct the showing of the number of RPC calls per second, as well as eliminate the use of erlang:now/0. --- lib/kernel/test/rpc_SUITE.erl | 41 +++++++++++++++++++++-------------------- 1 file changed, 21 insertions(+), 20 deletions(-) (limited to 'lib/kernel') diff --git a/lib/kernel/test/rpc_SUITE.erl b/lib/kernel/test/rpc_SUITE.erl index 7adef49014..867b448b36 100644 --- a/lib/kernel/test/rpc_SUITE.erl +++ b/lib/kernel/test/rpc_SUITE.erl @@ -456,32 +456,33 @@ called_throws(Config) when is_list(Config) -> call_benchmark(Config) when is_list(Config) -> Timetrap = ?t:timetrap(?t:seconds(120)), - ?line PA = filename:dirname(code:which(?MODULE)), - ?line {ok, Node} = ?t:start_node(rpc_SUITE_call_benchmark, slave, - [{args, "-pa " ++ PA}]), + PA = filename:dirname(code:which(?MODULE)), + {ok, Node} = ?t:start_node(rpc_SUITE_call_benchmark, slave, + [{args, "-pa " ++ PA}]), Iter = case erlang:system_info(modified_timing_level) of undefined -> 10000; - _ -> 500 %Moified timing - spawn is slower + _ -> 500 %Modified timing - spawn is slower end, - ?line do_call_benchmark(Node, Iter), + Res = do_call_benchmark(Node, Iter), + ?t:stop_node(Node), ?t:timetrap_cancel(Timetrap), - ok. + Res. do_call_benchmark(Node, M) when is_integer(M), M > 0 -> - do_call_benchmark(Node, erlang:now(), 0, M). - -do_call_benchmark(Node, {A,B,C}, M, M) -> - ?line {D,E,F} = erlang:now(), - ?line T = float(D-A)*1000000.0 + float(E-B) + float(F-C)*0.000001, - ?line Q = 3.0 * float(M) / T, - ?line ?t:stop_node(Node), - {comment, - lists:flatten([float_to_list(Q)," RPC calls per second"])}; -do_call_benchmark(Node, Then, I, M) -> - ?line Node = rpc:call(Node, erlang, node, []), - ?line _ = rpc:call(Node, erlang, whereis, [rex]), - ?line 3 = rpc:call(Node, erlang, '+', [1,2]), - ?line do_call_benchmark(Node, Then, I+1, M). + {Micros,ok} = timer:tc(fun() -> + do_call_benchmark(Node, 0, M) + end), + Calls = 3*M, + S = io_lib:format("~p RPC calls/second", [Calls*1000000 div Micros]), + {comment,lists:flatten(S)}. + +do_call_benchmark(_Node, M, M) -> + ok; +do_call_benchmark(Node, I, M) -> + Node = rpc:call(Node, erlang, node, []), + _ = rpc:call(Node, erlang, whereis, [rex]), + 3 = rpc:call(Node, erlang, '+', [1,2]), + do_call_benchmark(Node, I+1, M). async_call(Config) when is_list(Config) -> Dog = ?t:timetrap(?t:seconds(120)), -- cgit v1.2.3
