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.

While the chart above is a good start, there’s more than simply considering “Reserved vs. On Demand”. So let’s take a closer look at all the options…
You may find useful new EC2 instance family equipped with local NVMe storage: **C5d**. See announcement blog post:
Ah, I'm having the same problem! Which C series did you pick?

While we’re at it, here’s a comparison of the old `c1.xlarge` with the new `c3.2xlarge` which are also about the same cost with similar benefits for switching:
Coming out of Phoronix today for helping you measure cloud performance are benchmarks of all the new C3 instance types and compared to some bare metal systems running locally.
I benchmarked all these new instances: c3.large, c3.xlarge, c3.2xlarge, c3.4xlarge, and c3.8xlarge.
While we’re at it, here’s a comparison of the old `c1.xlarge` with the new `c3.2xlarge` which are also about the same cost with similar benefits for switching:
To note how variable the price is, the C3.2xlarge is currently costing $10/hour spot price (meaning someone is paying that) while it normally costs $0.6 per hour.
For, e.g., the Rodina CFD benchmark, it would be interesting to see the difference between the generic "vanilla -O3" optimized executables and SandyBridge/IvyBridge "O3 AVX" optimized executables for both the 4960X and the (ought-to-be-comparable) c3.2xlarge.

The C3.2xlarge instances have High Network Performance. If you are copying images onto and off these boxes you will see better performance with these.

EC2 instances are priced according to instance type, regardless of the number of CPUs enabled. Disabling vCPUs does not change the cost of the instance type.
