[support] MyISAM vs InnoDB

[Earnie Boyd]

Quoting Daniel Carrera <daniel.carrera at theingots.org>:

>> For high performance, and transaction integrity many people move their

>> InnoDB uses ~5x the disk space and ~3x more memory. It can be faster,
>> and more reliable. But the down side is that if big tables like node,
>> watchdog are InnoDB you can run into problems. Based on your site
>> size, I don't forsee moving your entire site to InnoDB to be a
>> problem.

I use InnoDB myself.  I suggest the innodb_file_per_table configuration 
option to help control the size issue.  If you create a table and then 
remove it this option will return all the disk space, otherwise you 
continue to use it.
