Cloud Mercato tested CPU performance using a range of encryption speed tests:
Cloud Mercato's tested the I/O performance of this instance using a 100GB General Purpose SSD. Below are the results:
I/O rate testing is conducted with local and block storages attached to the instance. Cloud Mercato uses the well-known open-source tool FIO. To express IOPS the following parametersare used: 4K block, random access, no filesystem (except for write access with root volume and avoidance of cache and buffer.

yeah, but even if it is a random second cpu you might end up on one where another user is using the other thread at 100%. so i guess if you are lucky m4 might perform the same.

M4 is the lowest General Purpose CPU that is not burstable, and the m4.large current cost is $0.10 / hr.

You can use a master node (m3.large or m4.large or even m3.medium) and at-least 2 core/task nodes (m4.xlarge or m3.xlarge or c4.2xlarge).
