Here's what happened:

  1. I spun up an EC2 instance
  2. I successfully installed Ghost on it (a self-hosted blogging platform)
  3. I lost my *.pem private key that gives me access to the EC2 intance
  4. I ran the AWSSupport-ResetAccess automation service to recover the password
  5. I successfully recovered the password

However, if I open any page on my blog now, it takes more than 10 seconds to load. In my admin dashboard, I can't make any edit - it returns server errors every time I hit save.

I know that there can be many reasons for the cause of this lag, but I thought to ask this question in case this is a common problem? Is the AWS System Manager known to cause this lag to EC2 instances after an automation flow is executed?

I'm running a t2.micro Ubuntu 18.04 machine in the "eu-west-2" region.

  • If you run "top" is anything using excessive CPU? In Cloudwatch does your instance have available CPU / EBS credits or is it running on baseline CPU? A stop / start of the instance might be worthwhile - stop/start is different from a restart in AWS. – Tim Nov 14 '20 at 22:15
  • Doesn't look like anything unusual to me, [here's a screenshot](https://imgur.com/a/0CnYEO7). I'll try stop it and start it again, I didn't know that's different to a restart. – Paul Razvan Berg Nov 14 '20 at 22:20
  • Update: nah, stopping and starting didn't help. It's as low as before :(. FWIW I also tried updating all Linux packages and Ghost itself, didn't help. The AWS ResetAccess cannot be a coincidence .. – Paul Razvan Berg Nov 14 '20 at 22:32
  • Also, this is what it shows when I run `top`: [screenshot](https://imgur.com/a/WYE5TsX). – Paul Razvan Berg Nov 15 '20 at 00:05

    Interesting. Check your EBS burst balance. You could restore an EBS snapshot to another instance to compare performance, but if you can't log in maybe not helpful. You could build a new instance and migrate your data over to see if it helps. I think the answer to your question is "no it doesn't do that", and there's not enough information to help with the performance issue. – Tim Nov 15 '20 at 04:18
  • Thanks Tim for your insights. I will answer my question if I figure out what's the problem. – Paul Razvan Berg Nov 15 '20 at 11:01
