Slow Initialize on EC2 (Windows Server)
Posted: Mon Oct 20, 2025 1:20 am
We are using VMProtect 3.8.9 version.
Initialize takes too long when running VMProtect on an EC2 instance. (c7i.2xlarge)
It takes 30 seconds to 1 minute or more to pop up UI.
(It is same to run VMProtect itself without opening a project.)
After execution, the Task Manager shows that the VMProtect process occupies 100% of one CPU core in the background, and after more than 30 seconds, the UI pops up and reduces CPU occupancy. (Console versions also take a long time to run.)
Instance performance is sufficient, so it's not a performance issue.
For your information, the same Initialize delay occurred in the 3.9.6 version demo,
When using version 3.5, initialization was completed within 5 seconds without delay.
Could you tell me the cause of bottleneck when initializing in EC2 environment?
Also, what steps should we take to address this?
