The profiling results are split into three main categories: 
speed
, 
bandwidth
 and 
unindexed queries
:
• The speed category contains data about reading speed, write speed and broadcast 
speed.
• The bandwidth category profiles database data consumption across incoming and 
outgoing operations.
• Finally, the unindexed queries category contains data about unindexed queries 
since those queries can be expensive.
Op/mizing
The best way to optimize performance is to gather all of the data from the tools 
mentioned above. After you have gathered the data find out about best practices in 
the area that you want to improve and make changes accordingly.
Other ways of optimizing performance that were already mentioned in this section 
are sharing data across multiple database instances, building efficient data 
structures, query indexing, etc.
To learn more about optimizing database performance check out the official 
documentation on optimization, here:
