How to improve iDash performances?
The following index has been added in iDash Release 12.0.4 and allows to improve iDash performances:
create index idash_run_ins_start_index on idash_run(instance, start_time );
In case you are currently running an IDash Release older than 12.0.4, you can add this index manually in order to take advantage of this improvement.
I hope this can help.
