How big is the server/database that this data is in.  That table is only 120mg worth of data, really not that much.  It seems you would be better off finding other items to clean up then this table, unless this is a 500mg harddrive.  I agree with Gail, that index has not been rebuilt recently or inserts are that intense.  I would run dbcc dbreindex ('actions','',80) to set the default fill factor back to 80.
