Gene, doesn't that depend on how you want to use the index?
I have had VERY good performance with the following settings:

    CPYBLA     CRT-OBJECT-TYPE  , X'0E0A'; /* USRIDX */             
    CPYBLA     CRT-CREATION-OPTS, X'A0040000'; /* PERM */           
    CPYBLA     CRT-RECOVERY-OPTS, X'00000000'; /* DFLT */           
    CPYNV      CRT-SIZE-OF-SPACE,   4096;   /* EXTENDS AS NEEDED */ 
    CPYBLA     CRT-INITIAL-VALUE, X'00';                            
    CPYBLA     CRT-PERFORMANCE  , X'00000000';                      
    CPYNV      CRT-EXT-OFFSET   ,   0;                              
    CPYBWP    .CRT-CONTEXT      , .CONTEXT;                         
    CPYBWP    .CRT-ACCESS-GROUP , .NULL;                            
    CPYBLA     CRT-INDEX-ATTR   , X'20'; /*  INSERT BY KEY  */      
    CPYNV      CRT-ARGM-LENGTH  ,   16;  /*  10 KEY, 6 DATA */      
    CPYNV      CRT-KEY-LENGTH   ,   10;                             
    CRTINX    .INDEX, .CREATE;
