Welcome to the Lounge

Thanks for all, my challenge is the below code. If I am not using it then SP is taking 6 seconds to get data and after using it, taking more then 1 min
Please do you have any idea to optimize it

----------------------------------------------------
Update TMP1

Set DriverID = FDR.DriverID,
CompanyID = CDT.CompanyName
from @TempTable1 TMP1

   Inner Join (Select FaxID, CompanyID, LTrim(Replace(Stuff((Select  ', ' + ISNULL(Cast(FD1.DriverID as varchar(10)),'') From FaxId_Document_Relation FD1 Where FD1.FaxID = FD2.FaxID For XML PATH ('')),1,1,''),' ,','')) as DriverID

                    From FaxId_Document_Relation FD2
                      Where FaxID in (select FaxID from @TempTable1) 
                  Group By FaxID, CompanyID) as FDR ON TMP1.FaxID = FDR.FaxID
      --Inner Join CustomerDetails CDT on CDT.CompanyID = FDR.CompanyID --Anoop
	  Inner Join (select CompanyID, CompanyName from CustomerDetails) as CDT on CDT.CompanyID = FDR.CompanyID
