Feed cache:

This will clear all cached copies of feed data from the WordPress database and force FeedWordPress to make a fresh scan for updates on syndicated feeds.

Guid index:

Creating this index may significantly improve performance on some large FeedWordPress installations.

You have already created an index on the guid column in the WordPress posts table. If you'd like to remove the index for any reason, you can do so here.
Logging:
Debugging mode:

When debugging mode is ON, FeedWordPress displays many diagnostic error messages, warnings, and notices that are ordinarily suppressed, and turns off all caching of feeds. Use with caution: this setting is absolutely inappropriate for a production server.
