I  gave a lightning talk on MySQL Innodb and how realestate.com.au
  configures their databases to the DevOPS
  Melbourne meetup last night.
  
  My slides can be found here.
  
  Simply some take aways are
  
- Use Innodb for everything (unless another engine is appropriate)
- Having the working set in bufferpool makes MySQL Innodb fast by eliminating those foreground randrom reads of tablespace
- Use a RAID controller with BBU and write back cache for transactional log performance
  
  Thanks To Evan Bottcher for owning and organising the
  meetup!
