- Enabling backups in RDS requires enabling binlogs. So, with/without binlogging you will see different io pattern.
- Also, you don't state the IOPS for 'RDS1' or your self managed ec2. These are important details for your question.
- 'RDS2' is a 100g gp2 volume, so you need to look at the BurstBalance to be sure that you are not running out of Burst IOPS.
- Finally, IOPS < 0.5 is essentially an idle instance. It is unlikely with any configuration that your massive update workload is active and the IOPS is near zero.
Hope that is helpful.

Hi Phil, thanks for your answer but the problem is not in what I see in logs but the performance of my workload. So I rewrite my question to make it clearer
