Hi, I set up 3 Server nodes(8 cpu, 1gb ram) in the same server. 2 table each 10000 rows are entered.
When I perform a *SQL Join* query on two table and run it 100 times, I found that the first query is much slower than other(i.e. First query used 13s & other used around 0.02s). Why will it happen? Can I reduce the running time on 1st query?
