We can launch pre-configured Windows 2016 AMI instances via the EC2 plugin but individual pipeline steps take orders of magnitude longer to complete than expected.
To perform an httpRequest step takes 3-4 minutes. I can download the same file on the agent mid-build in less than one second.
Restoring a stashed file takes a minute and a half. No way that should be the case.
I have already gone through the Task Scheduler and disabled a bunch of processes that might slow the instance down on first boot. I have also launched the instance well in advance of need it as an agent, with no improvement.
Any ideas on what's left to try?
Thanks,
James
