: realize that dynamic fields made it worse.

dynamic fields don't make it worse ... the number of actaul field names 
you sort on makes it worse.  

If you sort on 100 fields, the cost is the same regardless of wether all 
100 of those fields exist because of a single <dynamicField/> declaration, 
or 100 distinct <field/> declarations.
