JDBC Connection from MySQL database to Spreadsheet very slow - mysql

Question

I have created this script to push the data from my MySQL database to google spreadsheet.
Now, to be updated, I have created a trigger every 5 minutes to run the script, but strangely when I see the executions of the trigger, it run approximately every 40 minutes.
The run of the script is approximately 2 minutes and so after this it push the data in the spreadsheet.
Is there something wrong with the script?
And how can I enforce the update duration that I have established in the trigger?
