Terraform-provider-aws: Heavy Cpu Load
Terraform Version
Terraform v0.10.8
Affected Resource(s)
aws_instance
aws_ebs_volume
aws_volume_attachment
general terraform issue
the aws plugin take ~16% and terraform master process take another 16%
Terraform Configuration Files
Debug Output
Please provider a link to a GitHub Gist containing the complete debug output: https://www.terraform.io/docs/internals/debugging.html. Please do NOT paste the debug output in the issue; just paste a link to the Gist.
Panic Output
If Terraform produced a panic, please provide a link to a GitHub Gist containing the output of the crash.log.
Expected Behavior
Terraform should not be taking 30% of my cpu just to start a couple of instances at aws.
This seems like excessive cpu load.
if I understand correctly, terraform is a wrapper around aws api, with a bunch of sophisticated logic ontop.
my cpu is a: Intel(R) Core(TM) i7-6820HQ CPU @ 2.70GHz
ram: 16GB
Actual Behavior
very high (37% peak) cpu load
Steps to Reproduce
Please list the steps required to reproduce the issue, for example:
terraform apply
Important Factoids
very basic aws configuration, with handful of remote exec to setup puppet. booting 3 instances using count variables. One instance has an attached ebs volume.

Hi @jgrammen-agilitypr!
I agree that this CPU usage seems excessive. Unfortunately, with the information given it's hard to guess what aspect of Terraform's work here was causing all this CPU work. If you're able to share a small config that causes this problem for you, we may be able to reproduce it and understand via profiling which aspect of the AWS provider and Terraform is using the CPU here.

Thanks for the additional information, @jgrammen-agilitypr.
When we get a chance we'll try to reproduce your results and, if we can, try to diagnose with a profiler.

Hello everyone.
I also have CPU load (100%, screenshot in attachment), but in my case I have not very strong CPU (i5-7200U).
I use Ubuntu subsystem on Windows 10.
ghost
on 22 Jan 2018
I am also getting high CPU utilisation running terraform. I am launching it from withing WSL Ubuntu on Windows, I get 100% CPU utilisation on all cores whilst terraform is sitting at the apply prompt.
Plan: 1 to add, 1 to change, 1 to destroy.
Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.
Enter a value:
The CPU utilisation appears to be occurring in the kernel (it shows as red in Process Explorer).
Something terraform is doing is causing the kernel to be very busy.
Whilst waiting for user input before doing anything should require ~0 CPU utilisation.
As soon as I answer no or hit ctrl-c the high CPU load stops.
I'm not using the AWS provider, I'm not sure if the underlying root cause of OPs problem is the same or different.

I will provide more details later, but this appears to be a real problem.
When running a terraform up, it appears that terraform is cpu limited.
I ran a up that takes 15 minutes but for a colleague it took 1.5 hours. He has a slower cpu (2 cores vs my 4 cores).
Terraform in my understanding is just parsing the terraform configuration and invoking provider api calls, why the crazy cpu usage?

Test terraform project
I built a brand new project just for testing purposes, with the minimalist configuration I can think of, and the cpu utlizations is still crazy high, for why should be api calls to aws.
It seems even more strange the the high cpu happens before I even accept the apply.
That means terrform is using tons of cpu just waiting to actually do anything.
This is now impacting our ability to use terraform, because colleagues with really beefy cpus are unable to use terraform to build our infrastructure.
cpu utilization while terraform is waiting for me to type yes, to accept the apply:

@jgrammen-agilitypr try strace -c -f, I suspect you'll see epoll_wait has the highest count. WSL has had several epoll bugs. I suspect this is a bug in WSL.

based on @berney suggestion I tried the windows version of terraform. No high cpu utilization, using the same test project. This strongly suggests that its a WSL bug, and everyone else who complained about high cpu in this thread were also running WSL.
I will have opened a bug report with WSL : https://github.com/Microsoft/WSL/issues/3276
