I am staring at the t2.micro (the smallest available instance type) server running MySQL 5.5.40 (using the my-huge.cnf example configuration shipped with MySQL, which ironically matches t2.micro specs). Here’s why (as reported by Nagios for the last few hours):
Queries per second avg: 12888.839
The number is fluctuating between about 12,500 and 13,500. Server load is moving between 0.05 and 0.08.
I think this answers the question of whether or not I am happy with the Amazon EC2 instance performance with a “hell yeah!” bang.
