Great info all around! Thanks!
I managed to get 1800 instances spun up today, which I figure should be good for ~3.46 million PPD. I may be able to push up to 2500 instances, but need to see what 1800 does to my internet traffic first. I have 1Gbps / 40Mbps service from Comcast, so bandwidth isn't an issue, but they have a 1TB cap and I also like to stream video and I work from home. I can't go over my cap.
I know it's our fault but this project is starting to test my patience. As soon as I get everything stable, it goes down for maintenance.
Sorry, missed this. As Skillz mentioned, I've booted back into Windows for the time being but even when in Linux I ran Windows VMs.
