Would performing daily optimizations of tables increase performance for MySQL and InnoDB? I have never did this before, but I have seen this module for Drupal http://drupal.org/project/db_maintenance, and it looks promising.
PS: As I learned, OPTIMIZE TABLE liberates overhead. However, I double checked the overhead column in mysql and it is all empty for my innodb tables ... So, I guess this may not be necessary.
Doing OPTIMIZE TABLE mydb.mytable; performs two basic operations
ALTER TABLE mydb.mytable ENGINE=MyISAM;
ANALYZE TABLE mydb.mytable;
This definitely cleans up table fragmentation and computes fresh statistics for indexes
Doing OPTIMIZE TABLE mydb.mytable; performs two basic operations
ALTER TABLE mydb.mytable ENGINE=InnoDB;
ANALYZE TABLE mydb.mytable;
While this eliminates fragmentation, ANAYLZE TABLE is complete useless for InnoDB. I wrote about this a long time ago:

You should probably focus on tuning InnoDB's other aspects (See my Aug 04, 2011 post: Optimizing InnoDB default settings)
I also have posts in the Drupal StackExchange on opimizing MySQL

For it worth : I"ve ran optimize table on the main tables of a database who works under heavy load. The main tables have been under great load of inserts/updates/deletes. The optimize reduced the table sizes by 90% and improved the system performance by more than twice !
