Regions and Latency

For the best user experience, users need low network latency between their dev environment and their local machine. Many operations in the IDE or terminal require network packets to be sent between the local machine and dev environment. High network latency can make the IDE and terminal feel sluggish.

Follow these steps to optimize your setup:

1. Identify regions offering the best latency for your users
2. Verify these regions are among the supported regions
3. Contact Ona support if you need support for additional regions

Predicting Network Latency

Before deploying Ona Runners, you can measure network latency using these tools:

Latency Testing Tools

• Third-party websites (search for “aws latency test”):

  • CloudPing
  • AWS Latency Test
  • AWS Speed Test

• Command-line tools:

  • ping command (requires ICMP support)
  • httping (for HTTP/HTTPS-only networks)

Important Considerations

• Test results reflect latency from your location to AWS regions. If users are in different locations, have them run the same tests.
• Ona is designed to work with multipe regions by installing a runner in each region.
• VPN usage affects test results. Configure your connection to match your planned Ona usage:
  • Use VPN if you plan to connect to Ona through VPN
  • Disable VPN if you plan to connect directly

Measuring Network Latency

After deploying Ona Runners, you can monitor latency using:

• JetBrains IDE: Check the “backend status” view when connected to a remote dev environment

Recommended Latency Thresholds

Latency	Experience	Recommendation
< 70ms	Excellent!	Ideal for all development tasks
< 120ms	Good	Suitable for most development work
< 200ms	Ok	Users may notice some latency in IDE and terminal
> 200ms	Poor	Not recommended. Users will experience significant delays
