Someone has experienced the same frustration with the meaning of event name and logged an idea that you may want to vote up
From my experience, if you double-click on event-name, it will be added into the viz and adds more context on what "Other" is doing.
You can get more detail out of performance recordings by following the steps:
1) Open the recording in Tableau Desktop and add a new worksheet
2) In the Dimensions or Measures pane on the left, right-click and select Show Hidden Fields.
3) You will now see a lot of new data that may provide more insights. You need to manually Unhidden any fields you want to use.
For collecting performance recordings on Tableau Server I would also advise appending the below string to the view URL:
This will disable cache from shared sessions and refresh the data in the view, so you will have a more accurate performance recording that is not dependent on cached queries and results.
I hope this information helps.
Thanks for the tip. Actually brings up more questions. Any idea what the Task Name 'Getting world update' is doing?
I think I'm starting to better understand how these events are structured, some are higher level groupings of sub-events.
It looks like my workbook loading is compiled of 3 main tasks:
VQLSession_LoadWorkbookFromFile - 8 secs
bootstrapSession_connectDataSources - 10 secs
VQLSession_GetWorldUpdate - 13 secs
It would be interesting to know what each stage is actually doing. VQLSession_GetWorldUpdate looks to be the physical building of the view, a lot of query execution happens at that stage.
bootstrapSession_connectDataSources is a little confusing as I wouldn't expect it to take 10 secs to connect to a published data extract. The actual Connecting to Data Source event occurs here, but that takes less than 2 secs. There are multiple other events, with the count of occurrences alongside, within that such as ColumnMetadataFixer (263), DashboardController_OnObservableNotify_ModelStateChangedMsg (1018), DataSourceParset_ParseFieldsOrDependencies (163), NamespaceInfo_Construct (264), VisualControllerHandleEdits (168), sort_make_buckets (138) and a few other events happening over 100 times.
VQLSesion_LoadWorkbookFromFile - not sure what this is doing
