Hi everyone 
Vaperina moved to a new server early this morning, which I’d like to briefly introduce so you can see what has changed behind the scenes.
Why was the move necessary?
Vaperina is a community site that runs several resource-intensive components in the background:
- web application (Unicorn)
- background processes (Sidekiq)
- database (PostgreSQL)
- image processing, search
- etc.
The previous server was already approaching its reasonable capacity limits, so the goal was to switch before problems appeared.
What is the new server like?
The site now runs in a more modern, higher-performance environment:
- more CPU cores (dedicated) → better parallel serving
- more memory (dedicated) → more efficient caching
- faster NVMe storage → faster database operations
Old → New
CPU architecture: Intel Xeon → AMD EPYC 9645
CPU: 2 vCPU → 8 vCPU (dedicated)
RAM: 4 GB DDR4 → 16 GB DDR5 (dedicated)
Storage (NVMe): 128 GB → 1 TB
The new server runs on a modern AMD EPYC-based infrastructure with dedicated CPU and memory resources, resulting in noticeably faster and more stable operation even under load.
What does dedicated resource mean?
This is a guarantee of stability. It means these resources are not shared with others; the server’s full power is available 100% for Vaperina, thus avoiding slowdowns caused by other sites and allowing us to consistently deliver the same performance.
System tuning
Several system parameters were retuned during the migration:
- optimized PostgreSQL memory usage
- more web workers
- larger safety buffer (swap) for stability
What does this mean in practice?
- faster page loading
- more stable operation under higher load
- fewer unexpected slowdowns or outages
- a better foundation for future development
Data security
No data loss occurred during the migration.
I am continuing to monitor the site’s operation to ensure everything is in order.
If anyone experiences anything unusual, please feel free to report it.
Thank you
