Re: [ovirt-users] ovirt-webadmin is too slow

we have done a few optimizations to the overall loading time of the application, a couple [1] in 3.5, another one [2] will be available in 3.6. 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 seamless. 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 [3], the fact that this is a pretty advanced Firefox on a deprecated Windows OS [4], etc. there is also a ux problem of contents in the page being highlighted sometimes when doing multi-selection [5] - 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. ---- Regards, Einav [1] https://gerrit.ovirt.org/#/c/30710/ , https://gerrit.ovirt.org/34703 [2] https://gerrit.ovirt.org/#/c/34193/ [3] 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.
