AWS C3.2xLarge instance Benchmark - http://blog.flux7.com/blogs/benchmarks/benchmarking-network-performance-analysis-of-c3-instances-using-iperf-tool

Note : We have downgraded the servers to M3.Large and the servers are currently in shutdown mode (not being used, until next testing). Still trying to find cost effective way to get maximum performance.
We are continuously Searching for best cloud service provider who can give us 10Gig network connectivity at a nominal cost.

* -> For Temporary Autoscaling or Batch Jobs only

Compute Engine might terminate (preempt) these instances if it requires access to those resources for other tasks. 
Additionally, Compute Engine has a finite number of available preemptible instances, so you might not be able to create them during peak usage.

Please note we are avoiding Local SSD due to reliability reasons. -> https://cloud.google.com/compute/docs/disks/#localssd

Also to note Google Provides sustained use discount (not for Preemtible Instances)
