Lookup Table vs Summary Index

[Sriram]

I want to create a summary index using a scheduled daily saved search and use in the dashboard view.I can accomplish this using a scheduled daily saved search and create a lookup table as well.In terms of performance, which one is preferable.

For eg.
I have a scheduled search which either build a summary index daily or build a lookup table daily.
Prior to that, I want to wreck and rebuild the summary index and lookup table daily as well.

Using Lookup table
