I tried Tokudb as well and below are the stats comparison for complex SUM and COUNT query. Please note that the number of rows and size is exactly the same and there is a partition on a Date column

Table size 10GB and rows 12 Million

Also note that I am using the default settings of Tokudb

With Tokudb - 1 min 41.38 sec With Innodb - 58.17 sec

So almost double.
