 * Hi Hector,
 * while trying to optimize my webite, I found that I didn’t use your optimisation
   tools up to now. So, in order to understand correctly how “Data sampling” is 
   working, I have two questions:
 * 1. When I enable data sampling with a sampling rate of 10, does that mean, that
   the amount of data stored in the database will be reduced by a factor of 10? 
   Because there will be only one record being stored instead of 10?
 * 2. Is it possible to switch data sampling on and off without loosing any old 
   data? Does WPP handle both data formats in the same way?
 * Thank you for your time and best regards, Tooni

 * Hey [@tooni](https://wordpress.org/support/users/tooni/),
    1. Yep, that’s basically it.
    2. Yes. Existing data won’t be altered by enabling/disabling the Data Sampling 
       feature so feel free to experiment with it as much as you need to.

 * Thank you very much, Hector.
    In the meantime I also enabled the caching option,
   which resulted in a fantastic improvement. Should have done this before… Together
   with data sampling it will be perfect. Regards, Tooni
