I want to setup a proxy (using Squid) that will take ~ 5000 requests per day on an Amazon EC2 instance. Will there be a noticeable difference in speed between a micro vs small instance?
The requests are for HTML, not for any media like images or videos.
Micro instances main issue is spotty CPU and disk I/O performance, but that amount of traffic is actually quite small, averaging 3 requests a minute. As a bonus, a micro instance will qualify for Amazon's free tier. For optimal performance, make sure the machine is stripped down of unnecessary services.
