how are you getting to 2400-3600 wu consumed when one search is 5-7wu?

are you doing the search within each row of the repeating group?

are you doing the search multiple times? - possibly because of reuseable elements or page reloads or group data changes - forcing searches to be refetched?

I wouldn’t try and hold 1600 records on a page - I don’t know why you’d need to do that.

search for task - constrained to status, priority, client
client = value of dropdown or search box

drop down or search box should be a search that uses ~5 wu
tasks should use about ~5wu

so total should be around 10wu + data - no where near 2400-5000wu

the issue is what are you doing on the page that is multiplying the search to use 2400 wu (assuming it is the search that is the issue there and not something else)
