How to speed-up CALC Dim and/or AGG Dim

Question

Hello Everyone,
I am new to Essbase and apologize for such a generic query. I came across a calculation script that takes more than 10 hours to execute. The crux of the script is CALC Dim (DIM) where DIM is a dense dimension with 11 levels (and a lot of calculated members). Can anyone guide me about the approach to be adopted to optimize the script. I was fiddling around with CALCCACHEHIGH parameter in essbase.cfg file and the SET CACHE HIGH declaration in the script. Will that help?
Some details of the original script are outlined below. The basic optimization parameters are in place (like the dense dimensions are at the end of the FIX list etc)
Thanks.

Script details:
SET AGGMISSG ON;
SET CREATENONMISSINGBLK ON;
SET UPDATECALC OFF;
SET FRMLBOTTOMUP ON ;
SET CACHE ALL;
SET CALCPARALLEL 5;
SET CALCTASKDIMS 2;
SET LOCKBLOCK HIGH;
FIX (&pln_scenario,"BU Budget",&plan1_yr,@RELATIVE("Product",0), @RELATIVE("YearTotal",0),... etc
CALC DIM ("Account");

Hi,
Thanks for your suggestions. I will definitely try to implement them and post the results. Meanwhile, here's another script which should not take too long to run. However, this script runs for hours. Any suggestions would be great (this does not have the cache options implemented yet). I have added some more details about the dimensions involved.
Outline of the script:
/*Script Begins*/
SET UPDATECALC OFF;
SET CACHE ALL;
SET CALCPARALLEL 5;
SET CALCTASKDIMS 2;
SET NOTICE LOW;
SET MSG SUMMARY;
FIX (@ATTRIBUTE("Existing"),@Relative("DC",0),@RELATIVE("PCPB",0),&pln_scenario,"BU Budget",&plan1_yr,@RELATIVE("YearTotal",0))
FIX(@RELATIVE ("RM",0))
SET CREATENONMISSINGBLK ON;
"RMQ" = "DC wise Sales Volume"->"UBOM" * "RMQ per Unit SKU"->"All DC"->"YearAgg";
ENDFIX;
ENDFIX;
/*Script Ends*/
