PWAIT_ALL_COMPONENTS_INITIALIZED and WAIT_XTP_HOST_WAIT high average ms per wait
I ran exec sp_BlitzFirst @SinceStartup = 1, @OutputType = 'Top10' and got the below output. Everything seems good except I dont know what PWAIT_ALL_COMPONENTS_INITIALIZED or WAIT_XTP_HOST_WAIT is and it seems high. Are those concerning and what are they?
IMHO, these are not concerning, and I base that on the research Paul Randal has already done.
PWAIT_ALL_COMPONENTS_INITIALIZED (Waits Library)
This is a wait you'll see during SQL Server startup. Not much you can do about it even if you do believe it is causing other problems (and I seriously doubt that it is). Paul completely filters this out as a benign wait in all of his waits analysis.
WAIT_XTP_HOST_WAIT (Waits Library)
Paul also filters out WAIT_XTP_HOST_WAIT in all of his waits analysis because it is a non-actionable wait involved with regular Memory-Optimized table mechanics.
I would seriously adopt Paul's set of filters in your regular waits analysis toolkit so you're only looking at waits that (a) are a problem and (b) you can do anything about.
