MyISAM multi queries slow performance
I am currently using MySQL Workbench of AWS to process data. I created my code as stored procedures with parameters so that I can call it to process. The thought of this function is that it sliced the main tables into multiple sub_tables based on the parameters entered and created their own temp tables to process.
Lets say that without splitting the jobs it takes 312s to complete and when I split it into 7 instances to run simultaneously, it takes 183s for them to complete ( I was expecting to achieve a similar result like 312/7 = 45s around).
I manually open multiple connections in MySQL both and they delivered similar results, which was not as good as I thought.
Can anyone help to explain?
Appreciated
