Slow response of ALV report for a high volume internal table

We have a requirement in which we have to display more than 5 lac records (= 500,000) in a single alv report. The internal table has 30 fields. it takes around five minutes to display the alv.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'

EXPORTING

i_callback_program = l_repid

i_callback_pf_status_set = pfstatus

it_fieldcat = it_fcat[]

i_save = 'A'

is_layout = gs_layout

• is_variant = import_variant

it_events = events[]

TABLES

t_outtab = i_tab.

above is the code used to display the alv. Any change in the coding to be done to improve the performance?

Thanks in advance.
