From 69a44f9cfc569f447567179279363e608b53ff49 Mon Sep 17 00:00:00 2001 From: Robin Burchell Date: Fri, 9 Dec 2011 15:05:10 +0100 Subject: Change event posting to use a QVector. This provides a ~10% improvement to the newly introduced QCoreApplication event_posting_benchmark (a simple synthetic benchmark of creating a bunch of events, posting them, and sending the queue). before: ********* Start testing of QCoreApplicationBenchmark ********* Config: Using QTest library 5.0.0, Qt 5.0.0 PASS : QCoreApplicationBenchmark::initTestCase() RESULT : QCoreApplicationBenchmark::signal_slot_benchmark():"1000": 0.82 msecs per iteration (total: 53, iterations: 64) RESULT : QCoreApplicationBenchmark::signal_slot_benchmark():"10000": 8.6 msecs per iteration (total: 69, iterations: 8) RESULT : QCoreApplicationBenchmark::signal_slot_benchmark():"100000": 84 msecs per iteration (total: 84, iterations: 1) RESULT : QCoreApplicationBenchmark::signal_slot_benchmark():"1000000": 874 msecs per iteration (total: 874, iterations: 1) PASS : QCoreApplicationBenchmark::signal_slot_benchmark() PASS : QCoreApplicationBenchmark::cleanupTestCase() Totals: 3 passed, 0 failed, 0 skipped ********* Finished testing of QCoreApplicationBenchmark ********* after: ********* Start testing of QCoreApplicationBenchmark ********* Config: Using QTest library 5.0.0, Qt 5.0.0 PASS : QCoreApplicationBenchmark::initTestCase() RESULT : QCoreApplicationBenchmark::event_posting_benchmark():"1000 events": 0.781 msecs per iteration (total: 100, iterations: 128) RESULT : QCoreApplicationBenchmark::event_posting_benchmark():"10000 events": 7.8 msecs per iteration (total: 63, iterations: 8) RESULT : QCoreApplicationBenchmark::event_posting_benchmark():"100000 events": 75 msecs per iteration (total: 75, iterations: 1) RESULT : QCoreApplicationBenchmark::event_posting_benchmark():"1000000 events": 774 msecs per iteration (total: 774, iterations: 1) PASS : QCoreApplicationBenchmark::event_posting_benchmark() PASS : QCoreApplicationBenchmark::cleanupTestCase() Totals: 3 passed, 0 failed, 0 skipped ********* Finished testing of QCoreApplicationBenchmark ********* Change-Id: Ibf56d9526b0a8cbaf171008da4104bb457628172 Reviewed-by: Sergio Ahumada --- tests/benchmarks/corelib/kernel/kernel.pro | 3 +- .../corelib/kernel/qcoreapplication/main.cpp | 82 ++++++++++++++++++++++ .../kernel/qcoreapplication/qcoreapplication.pro | 9 +++ 3 files changed, 93 insertions(+), 1 deletion(-) create mode 100644 tests/benchmarks/corelib/kernel/qcoreapplication/main.cpp create mode 100644 tests/benchmarks/corelib/kernel/qcoreapplication/qcoreapplication.pro (limited to 'tests/benchmarks') diff --git a/tests/benchmarks/corelib/kernel/kernel.pro b/tests/benchmarks/corelib/kernel/kernel.pro index da3f0d609f..8b7d8c8f90 100644 --- a/tests/benchmarks/corelib/kernel/kernel.pro +++ b/tests/benchmarks/corelib/kernel/kernel.pro @@ -4,4 +4,5 @@ SUBDIRS = \ qmetaobject \ qmetatype \ qobject \ - qvariant + qvariant \ + qcoreapplication diff --git a/tests/benchmarks/corelib/kernel/qcoreapplication/main.cpp b/tests/benchmarks/corelib/kernel/qcoreapplication/main.cpp new file mode 100644 index 0000000000..e1e4e2cc9a --- /dev/null +++ b/tests/benchmarks/corelib/kernel/qcoreapplication/main.cpp @@ -0,0 +1,82 @@ +/**************************************************************************** +** +** Copyright (C) 2011 Robin Burchell +** All rights reserved. +** Contact: Nokia Corporation (qt-info@nokia.com) +** +** This file is part of the test suite of the Qt Toolkit. +** +** $QT_BEGIN_LICENSE:LGPL$ +** GNU Lesser General Public License Usage +** This file may be used under the terms of the GNU Lesser General Public +** License version 2.1 as published by the Free Software Foundation and +** appearing in the file LICENSE.LGPL included in the packaging of this +** file.
