Speed performance issues, database bloat, limited support

I have been using this product for about 6 years, but unfortunately it is getting worse and worse. The speed performance is getting worse, slowing my website down. There is a large database bloat that causes your database to load large amount of data for no apparent reason. This plugin so far is responsible for most of my load times, while I would expect other heavier plugins to cause more load. I have tried solving this with their support team but unfortunately they have not been able to resolve this. This plugin used to be pretty decent, but the performances issues make this much more doubtful. I would recommend testing your speed-performance before using this plugin, and look at alternative options.
