[ovirt-users] ovirt-webadmin is too slow

we have done a few optimizations to the overall loading time of the
application, a couple  in 3.5, another one  will be available
some of these optimizations made the initial loading time of each
main tab (i.e. first main tab selection right after login) a bit
slower, but after waiting for a *very* short period of time of
letting the main-tab finalize its loading, the ux should be fairly
I assume that some other factors may be affecting the ux, such as
the load on your engine server (you mentioned you have 120 VMs -
how many of them are up? how many Hosts do you have? how strong is
your engine server machine / how does the mem/cpu/net performance
of your engine-server machine look like? any suspicious messages
in your engine/server.log?), the connectivity between your engine-
server and your hypervisors, as well as between your engine-server
and your client , the fact that this is a pretty advanced Firefox
on a deprecated Windows OS , etc.
there is also a ux problem of contents in the page being highlighted
sometimes when doing multi-selection  - we are aware of that.
my recommendation would be to test a different client (preferably
Linux), ensure that the engine is not overloaded and ensure that
the engine <-> hypervisors connectivity and the engine <-> client
connectivity are reasonable.
Alexander (and/or others) can share thoughts as well, if any.

 from our experience, a 120ms engine<->client connectivity should
work pretty well, but a 220ms connectivity, for example, will be more
prone to ux problems such as a 'stuck' UI.
 Bug 1143922 - Selecting multiple objects via UI,colors screen with os-default-highlight-color [could be orange, could be blue, ...] highlighting which is visually displeasing
