Hi.
on windows that is even worse as  the 
qtdeclarative/tests/benchmarks/qml/librarymetrics_performance benchmark is 
crashing  in many testcases. 5.2.1 runs some more cases than 5.3.2 and 5.4 
beta. 
 
the test cases which crash in  5.3.2 and 5.4 beta are:
 //QTest::newRow("039) listView - with anchors and list model content with 
delegate") << testFileUrl("data/listview.3.qml");
// QTest::newRow("046) image - with content, async") << 
testFileUrl("data/image.4.qml");
// QTest::newRow("053) repeater - row - repeat simple rectangle") << 
testFileUrl("data/repeater.1.qml");
 // QTest::newRow("054) repeater - column - repeat simple rectangle") << 
testFileUrl("data/repeater.2.qml");
// QTest::newRow("058) positioning - anchored positioning") << 
testFileUrl("data/anchoredpositioning.qml");
 // QTest::newRow("059) positioning - anchored (with grid) positioning") << 
testFileUrl("data/anchorwithgridpositioning.qml");
// QTest::newRow("061) positioning - anchored (with binding) positioning") << 
testFileUrl("data/anchorwithbindingpositioning.qml");
 

// QTest::newRow("03) positioning - anchored positioning") << 
testFileUrl("data/anchoredpositioning.2.qml");
// QTest::newRow("04) positioning - anchored (with grid) positioning") << 
testFileUrl("data/anchorwithgridpositioning.2.qml");
 

// QTest::newRow("06) positioning - anchored (with binding) positioning") << 
testFileUrl("data/anchorwithbindingpositioning.2.qml");
// QTest::newRow("07) positioning - binding (with grid) positioning") << 
testFileUrl("data/bindingwithgridpositioning.2.qml");
 

 
 
I tried to let it run with 5.1 on windows but i am getting lots of weird 
warnings i dont understand:
 
Config: Using QtTest library 5.1.0, Qt 5.1.0
PASS   : tst_librarymetrics_performance::initTestCase()
QWARN  : tst_librarymetrics_performance::compilation(001) item - empty) ERROR: 
(file:///data/item.1.qml:3:1: Item is not a type
    Item {
    ^) 
 
 
where item.1.qml is just
importQtQuick2.0
 
Item{
}
 

i also get this for other types in the other tests. Furthermore i get:
QWARN  : tst_librarymetrics_performance::instantiation_cached(007) item - 
uninitialised Item prop) QQmlComponent: Component is not ready
a lot.
 
 
When looking at the all the perf numbers for 5.2.1 and 5.3.2, i can see that a 
lot are slower in 5.3.2 but only a few faster . Comparing  5.3.2 with 5.4 some 
are slower some are faster.

as for 5.1.0 , getting most of the time errors i dont count the result as 
reliable. 


As the positioner tests work for all, so here are these results


Qt 5.1.0 has

Qt 5.2.1 has much slower results:

 Qt 5.3.2 is even slower:

And Qt 5.4 is even more slower:
PASS   : tst_librarymetrics_performance::instantiation(056) positioning - no 
positioning)
RESULT : tst_librarymetrics_performance::instantiation():"056) positioning - no 
positioning":
