Total time, Execution time


#1

To cut it short: I did a performance test and discovered that GPU version of the MapD software is faster when speaking of execution time, however in terms of total time time it takes the GPU version almost as long as the CPU version. How is that possible?
(If that is already answered, please point me to the right direction)

Thanks in advance.

@Moses can you share a bit more about your parameters, such as:

  • Your environment?
  • Your datasets?
  • Your queries or dashboards?

Also, I forgot about this post, which may be useful. There are issues of first-time disk read vs in-memory execution, and a few other factors.
