On Oracle Health Sciences Translational Research Center (TRC) 3.0.2 version,

Queries or jobs are running slow in Cohort Explorer UI.

Expected that the Cohort Explorer UI should provide a faster response.

The issue can be reproduced with the following steps:
1. From TRC Cohort Explorer, go to "Single Subject Viewer"/"Circular Genomic Viewer" sub tab; 2.

    Select a Subject ID and a DNA Reference Version. click on "Submit" button.
    It takes more than 15 mins to return result back as well displaying the circular visualization.

2. Go to "Cohort Query" tab and perform the following selections.
   - Clinical Data > Specimen, Specimen Number: select all available specimens (over 45 specimens)
   - Study: select a study
   - Genomic Data > Sequence Variants:
     having Zygosity: select Zygosity
     at Genomic Position: select Genomic Position
     DNA Reference Version: 1
     Variant Status: select status
3. Run Query.

    The result take too long.

4. Go to "Cohort Query" and search for "Demographics" and search for:

    Gender: Female
    Age (years) > 50
5. Run Query.

    This only results 7 results.
    Then click "Cohort Report" to view the report for these 7 results.
    It will take several minutes. Report will be more slower if adding Sequence Variants and Gene Expression to the search for only one gene.

    This will take around 5 mins.
