How to fix slow UCSC performance?

Check Server Status

• Verify if the UCSC Genome Browser server is undergoing maintenance or experiencing widespread issues. Check official UCSC channels for announcements.

 

• Ensure your internet connection is stable. Sometimes, connectivity issues can be the real cause of slow performance.

Optimize Browser Settings

• Clear your browser cache and cookies. This can help resolve issues related to outdated files affecting performance.

 

• Disable unnecessary browser extensions that might be consuming resources and slowing down your web experience.

Use Sessions Effectively

• Limit the amount of data displayed in your sessions. Close any unnecessary tracks or tabs that aren’t needed for your current analysis.

 

• Save sessions frequently and clear any temporary or redundant sessions that may be consuming resources.

Adjust Track Display Settings

• Reduce the number of visible tracks. Only display tracks that are essential for your analysis to improve loading times.

 

• Change the display mode of high-density tracks from "full" to "dense" to reduce the amount of data being processed.

Utilize Downloadable Data

• Consider downloading data for local analysis. This can help avoid repeated server requests which can be time-consuming with poor connectivity.

 

• Use batch downloads when possible to avoid the need for continuous online access, reducing load times significantly.

Contact Support for Assistance

• Reach out to UCSC support if performance issues persist after troubleshooting. Provide them with details of the problem and any specific error messages.

 

• Stay informed with ongoing system updates from the UCSC team to keep abreast of performance improvements and new features.
