## Current Behavior

large data need like 100k data without using pagination. page hanging.

Reproduce the page-hanging behavior with about 100,000 rows and no pagination in the mui-datatables example or application setup. Then inspect the table's rendering path to identify what prevents large datasets from remaining responsive. Done means a documented, tested approach that supports this dataset without pagination and avoids the reported hang.
