Issue/Introduction

In MUX the user Group OBS permissions are adding a large overhead on MUX Grids (Project Grid), with even more performance impact with their custom OBS secure field added

STEPS TO REPRODUCE:

1. Connect to Clarity with user with Resource Global rights and no Group OBS rights 
2. Go to Project Grid in MUX
3. Open a presaved view that contains two Investment object custom Secure fields: a Lookup String and a custom OBS unit field. Also open a basic view just with Project ID and Project Name fields
4. Note they take 2-4 sec to load
5. Now log in with user with Group OBS permissions only and no Global permissions or Global Project Edit permissions

Expected Results: The views to be returned within reasonable time

Actual Results: The views with secure OBS fields take up to 74-78 sec. The basic view takes up to 35 sec.
