  1. Just wondering what that plugin does exactly. I am using it in hopes to make data retrieval faster. Will the plugin help in those respects?

  2. mrking, that depends, how much overhead can be freed.

    To explain, what an overhead is, I' cite an offline resource of mine:

    Every database will, over time, require some form of maintenance to keep it at an *optimal* performance level. Purging deleted rows, resequencing, compressing, managing index paths, defragmenting, etc. is what is known as OPTIMIZATION in mysql and other terms in other databases. For example, IBM DB2/400 calls it REORGANIZE PHYSICAL FILE MEMBER.

    It's kind of like changing the oil in your car or getting a tune-up. You may think you really don't have to, but by doing so your car runs much better, you get better gas mileage, etc. A car that gets lots of mileage requires tune-ups more often. A database that gets heavy use requires the same. If you are doing a lot of UPDATE and/or DELETE operations, and especially if your tables have variable length columns (VARCHAR, TEXT, etc), you need to keep 'er tuned up.
