    v11 v12  
    77||Create paint traces with a better data format. Currently a full trace will make the device go out of memory.|| ||
    88||loading_standalone was created to reproduce a loading issue with Wikipedia content. Currently it is not able to reproduce the exact same set of problems. The test should be changed to start new downloads from within didReceiveResponse... like in the real case.||[ Delete requests in each iteration] [ Use 4.7 API]||
     9||Create a netfilter userspace utility to add arbitary latency on a link. This can be used to see how the behavior of the various network tests change over time. ||[ Create netsim] [ Fix longer delay]||
    910||tst_painting is currently using ''QApplication::syncX'' in the performance run to make sure that everything has been synced. The problem with this paint benchmark is that on accelerated hardware it is not clear when the image has been painted. The ''QApplication::syncX'' will make the test a bit artificial in one way.||||
    1011||Benchmarks should generate more stable timing results. This is mostly with tst_cycling not being stable enough to use it for timing. The first change is to use the '''-median 5''' when executing the test and the second part is to disable the cache. The result is a lot more stable but it depends on the workload of the http_server as well. So there is more work left to do. ||[ Disable Cache]||
