Why simple query in memsql is slower than that in MySQL?

I would like to ask about the speed problem of memsql
This is a very simple query:
''select * from test_mission";
90000 piece of data;
The mysql take about 3.8s ,
but memsql take about 21.0s

I see,does memsql have visualization tools like Navicat for MySQL

The runtime of a query like that is normally dominated by the time to transfer the result set to the client. So what client drivers you’re using and your network/cloud configuration and where the client is running all could have an effect. MemSQL’s native query execution speed is typically much faster than MySQL across the board.

I’m not familiar with Navicat specifically but all kinds of BI and visualization tools that can connect to MySQL in general will work with MemSQL.
