One thing that helped (and helps) me a lot is a chess tree viewer. I started by just dumping XML code out of search and using a web browser to view it as a tree. Both IE and mozilla do a reasonable job allowing you to expand/contract branches etc... Then I got tired of this solution and hacked something together to give me a tree control and call winboard to show me the FEN when I clicked on it. I use this all the time when I'm thinking about pruning etc... The reason for this tip is that I strongly suspect your problem is in search and not move gen. Even if you wrote a terribly slow move generator you should not be taking 3 seconds to get a 4 ply search. I bet you're searching a ton of nodes and need to look at your move ordering / search tree.
