Not all cloud instances are created equal
You know how anecdotally we say, “in the cloud, bad nodes exist” so you should always get a baseline?
Today I ran a query (repeatedly) on sqlite3, and on two instances, I got time measured as:
Run Time: real 13.405 user 13.243332 sys 0.046667
Run Time: real 10.989 user 10.963332 sys 0.010000
This naturally skewed results I initially got for something related to MySQL/MariaDB benchmarking. It really was such that while I had 2 instances, in the same region/AZ, I had one “good” node and one “bad” node.
