Not true. On the "Instance Types" page they describe clearly: http://aws.amazon.com/ec2/instance-types/ Type Networking Performance t2.Micro Low to Moderate t2.Small Low to Moderate m3.Medium Moderate m3.xlarge High And so on... The point being, they do in fact prioritize network traffic in favor of larger more expensive instances. The first time I started observing the small instances being adversely affected was several months ago, I'm going to guess around Feb. I noticed that I could hit the company webpage, and sometimes it would load instantly, sometimes it would stall there for several seconds with a blank white page and then slowly load (as if I were on a 56k modem). We have some large-ish files for download on the website. 100M-200M. I noticed, that sometimes I would download the files at 2MB-3MB/sec, and sometimes it would come down around 15 KB/sec. Literally a thousand times performance variation, which varies minute by minute, hour by hour. You just never know what you're going to get. I would login to the server and run top, and I'd see plenty of ram available, mostly idle cpu, and no other signs of anything awry. _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
