Anonymous , I have use this code in the past and it worked fast

Switch Period =
var _max1 = if(isfiltered('Date'),MAX( 'Date'[Date]) , today())

var _max = if(SELECTEDVALUE(Period[PeriodType],"MTD") = "Yesterday",MAX( 'Date'[Date])-1 , today()-1)
var _min =
SWITCH(SELECTEDVALUE(Period[PeriodType],"MTD"),
"YTD",eomonth(_max,-1*MONTH(_max))+1 , //FY April -March
"FYTD",if( Month(_max) <4 , date(year(_max)-1,4,1) ,date(year(_max),4,1)), //FY April -March
"QTD",eomonth(_max,-1* if( mod(Month(_max),3) =0,3,Month(_max)))+1,
"MTD",eomonth(_max,-1)+1 ,
"WTD", _max -WEEKDAY(_max,2)+1,
"today", today() ,
"Yesterday", today()-1 ,
"Cumm", Minx(ALLSELECTED('Date'),'Date'[Date]),
"Rolling 3", date(Year(_max), month(_max) -3, Day(_max))+1,
"Rolling 6", date(Year(_max), month(_max) -6, Day(_max))+1,
"Rolling 12", date(Year(_max), month(_max) -12, Day(_max))+1,
BLANK())
return
CALCULATE([net] ,DATESBETWEEN('Date'[Date],_min,_max))

Try if these can help

Thank you. I did try this and seems to give some performance boost but analyzing with DAX Studio it would seem that the biggest drag on performance is going through multiple switch statements to control not only which measures I use for the period calculations and comparison period calculations but also which KPI I want to show (i.e. Sales or Margin). There is a big performance drag with the KPI Switch function.

I figured out my issue was that in my SWITCH statement I was using an index from my slicer tables (disconnected tables) but I used the period name to fitler directly on the report. The DAX optimization for SWITCH requires that you use the column that you're directly filtering on the report. So a very small change lead to huge increase in perofmrance. I might also try your formulas to see if I can squeeze out some more preformance. Thanks.
