Target release should be placed once a package build is known to fix a issue. Since this bug is not modified, the target version has been reset. Please use target milestone to plan a fix for a oVirt release. > Status: POST → MODIFIED
This bug was originally meant to collect all kinds of post-memory-leak-fix improvements.
Currently, it has 4 IE-specific patches associated. None of them is merged into master, so moving back to POST.
If we wish to proceed with those 4 IE-specific patches (only), maybe we should rename this bug.
All IE-specific patches verified on local Engine (master) build using IE11 / Windows 8.1 (thanks to Pavel Novotny).

Relevant patches are merged in master, updated BZ title. Verified in rhevm-4.1.1.2-0.1.el7.noarch Browser: Internet Explorer 11 @ Windows 8.1 Pro (4 vCPU, 8 GB RAM) RHEVM environment: 1 DC, 2 clusters, 1 host, 2 NFS storages (1 data, 1 export), 41 VMs (blank, w/o OS installed, 4 of them Up). I ran a test in a loop, where it went through the main tabs and then opened & closed the New VM dialog. After each pass I wrote down the memory usage from Developer Tools / Memory / Profiling session - Process memory usage (private bytes). I compared the data against rhevm-4.0.7.4-0.1.el7ev, which contains the same IE-related fixes, as well as against the "unfixed" released rhevm-4.0.6.3-0.1.el7ev (for differences between 4.0.6 and 4.0.7 see bug 1404610 comment 9). See the chart attached. With 4.0.7, the maximum I managed to run was 9 passes before reaching a RAM usage ~1.6 GB. This seems to be the browser limit, where it becomes unresponsive beyond usability and the app. eventually freezes or crashes. The 9 passes took 19 minutes. With 4.1.1, I managed to run 14 passes before reaching the 1.6 GB RAM usage. To compare with 4.0.7, 9 passes here took 12 minutes. All 14 passes took 25 minutes. Created attachment 1259245 [details]
