Hi ,
Thanks for reaching out to Microsoft Q&A.
Performance issues like slow workspace loading and long publishing times in synapse can arise due to several factors. Here are some potential causes and steps to troubleshoot and resolve them:
- Slow Synapse Workspace Load Time
Possible Causes & Fixes:
- Browser Cache Issues: Clear your browser cache and try using an incognito window.
- Too Many Artifacts (Pipelines, Notebooks, Datasets, etc.): Large numbers of resources can slow down workspace loading. Consider organizing or archiving unused artifacts.
- Network Latency: Test your network connection speed and consider using a VPN if accessing Synapse from a remote location.
- Azure Region Performance: If your Synapse workspace is in a region experiencing high demand, performance might degrade. Check Azure Service Health in the Azure Portal.
- Integration with External Services: Linked services or external dependencies (like Data Lake, SQL Pools, or third-party connectors) can slow down loading if they experience issues.
Troubleshooting Steps:
- Check Azure Service Health (Azure Status Page) for ongoing issues.
- Test in Different Browsers or Machines to rule out local issues.
- Disable Unused Extensions in Browser (ad blockers, VPNs, etc.).
- Check Azure Resource Utilization Metrics in Azure Monitor.
- Long Publishing Time to Master Branch
Possible Causes & Fixes:
- Large Number of Changes: If there are too many changes in Synapse artifacts, publishing may take longer.
- Git Integration Performance Issues: Slow sync with the remote repository can cause delays.
- Workspace Metadata Size Growth: Synapse stores metadata for linked services, datasets, and pipelines, which may grow over time and slow down publishing.
- Long-Running Dependencies: If you have dependencies such as Spark pools or SQL pools, ensure they are properly optimized.
Troubleshooting Steps:
- Optimize the Number of Changes – Commit and publish in smaller batches.
- Check Git Repository Performance – If using Azure DevOps or GitHub, check if the repository is slow.
- Monitor Synapse Logs - Use Synapse Studio --> Monitor --> Activity Runs for any errors.
- Reintegrate Git Repository – Disconnect and reconnect Git integration in Synapse Studio --> Manage --> Git Configuration.
- Check SQL/Spark Pool Health – Ensure SQL pools are paused when not in use and Spark pools are properly configured.
