I am developing an AIR app, and am wondering what people believe would be faster...I plan to implement an RSS reader in the app, and want to filter the entries that have been read/saved already, so I will need to do a lookup on every downloaded RSS item in a dictionary to see if the user has looked at that item already.
Would it be faster to read these in from the SQLLite DB at startup and check these in memory, or just perform queries on the SQLLite db directly? Thanks.
