We want to know how would be the performance of the new instance.
Performance of the new instance will be slightly better due to better AWS technologies and a greater max CPU frequency (3,1 Ghz for current, 3,6 Ghz for new (turbo)).
By the way, it's a good practice to upgrade EC2 instance to the newer one. Costs are lower (up to 35%) while performance are slighlty better.
