Export to CSV performance issue

Hi, Am using a default Export to CSV button in grid to download CSV file. Grid has 17 columns and NO calculated fields. But the download is taking almost 29 seconds for 850 records and am seing below message in logs: WARNING - ConnectionBus_Queries: Query executed in 28 seconds and 990 milliseconds: UPDATE "system$backgroundjob"  SET "endtime" = ?,  "successful" = ?,  "result" = - 850 records Sometimes this time gets increased and i get default system error occurred popup messages. Can anyone please tell me how can i increase performance of Export to CSV button?

try to add indexes to your domain modal. this might improuve a little bit the performance.
