Jacopo Cappellato commented on OFBIZ-5170:
------------------------------------------

{quote}At first I replaced all FastList instances with java.util.ArrayList. Profiling the change indicated longer AST. Then I replaced all FastList instances with java.util.LinkedList. Profiling the change indicated a shorter AST.{quote}

Adrian, this is interesting. However, the problem of selecting the best implementation for a List, doesn't have one solution that is valid in all the situations: for some usages arrays (i.e. ArrayList) are better, in some others linked lists (i.e. LinkedList) are better.
But I agree that it makes more sense to benchmark FastList with LinkedList rather than ArrayList because FastList is also a linked list implementation.
