Is there a better approach to show the distinct count measures?

Question

Experts,
I have a requirement in which I want to diplay 20+ calculated columns. The coulmns are something like this..
No of clients with income < 10000 (to check against sales measure in fact table)
No of Clients with sales > 500000 (to check against sales measure in fact table)
No of clients whose join date > 1st jan current year ( to check against cust_start_dt of client Dim)
No of clients with size "Medium" (to check agains a column client_size of Client Dim)
No of clients with sell product units > 500 (Need to check units in PROD Dim)
and so on..
Well, I can write a case statement using expression builder for each column in the criteria, but the report performance is very bad. My client dimension is a huge partitioned table. As I keep on adding columns, the report takes more time to fetch data and at some point it never comes back.
We tried to push to calculations to database, but since users can provide any selection criteria from dashboard prompt, it doesn't seem to work.
If anyone had done any similar request in the past, please direct.

Jared,
Thank you for responding to my posted message. Rendezvous is a new concept to me, maybe
it's the solution to my problem. I have been trying to read the on line manual and
example VIs from National Instruments website. I still have a hard time to understand
the concept.
One of the example I saw is using rendezvous to run some sub VIs. But in my case, I have
only one VI that is a while loop. Inside the while loop, there are a few tasks running
simultaneously. I don't know whether it will serve my purpose.
